Seite 128 - ... similar teeth. The tongue is smooth, flattened, tapering anteriorly. The mouth is moderate, the posterior extremity of the upper maxillary reaching a vertical which would pass in advance of the orbit only. The eye is subcircular, and well developed ; its horizontal diameter being contained a little over four times in the length of the side of the head. The anterior suborbital is broadly developed, overlapping considerably the upper jaw. Its external edge is minutely crenated. The serratures of...
Seite 56 - The nostrils, situated towards the upper surface of the head, are much nearer to the orbit than to the tip of the snout. Upper jaw overlaps the tip of the lower one ; the posterior extremity of the maxillary...
Seite 310 - Body very much compressed, rather deep upon its middle region, and quite tapering posteriorly. Head moderate, constituting the fifth of the entire length. Jaws equal. Maxillary slightly curved ; its free extremity extending to a vertical line drawn posteriorly to the orbit. Anterior margin of dorsal fin nearer the extremity of the snout than the insertion of the caudal fin. Bluish grey above ; silvery along the middle of the flanks ; yellowish beneath.
Seite 314 - Maxillary slightly bent? extending to a vertical line drawn inwardly to the posterior rim of the orbit. Jaws equal. Anterior margin of dorsal fin a little nearer the extremity of the snout than the insertion of the caudal fin. Back bluish grey ; upper surface of head blackish grey ; sides silvery grey ; fins ash grey; dorsal and caudal spotted.
Seite 226 - ... fin, is scarcely half the latter. The greatest thickness, upon the thoracic region, is a little more considerable than the least depth. The peduncle of the tail is flattened, and wedge-shaped towards the base of the caudal fin. The back is uniformly rounded or convex, and the ventral region narrow. The anterior margin of the dorsal fin is equi-distant between the tip of the snout and the base of the caudal ; its anterior margin is equal in height to its base, and its posterior margin is about...
Seite 182 - ... nostrils are small, and nearer to the tip of upper jaw than to the anterior rim of the eye. The anterior one is rounded, whilst the posterior one is subcrescentic and convex posteriorly. The eye is large and circular...
Seite 226 - ... palatines. The posterior nostril is the largest, subtriangular in shape, and situated close to the anterior rim of the orbit ; the anterior nostril is circular, and opens a little in advance of the latter. The eye is subcircular, approximating the upper outline of the profile; its horizontal diameter enters five times in the length of the Side of the head. The inferior edge of the suborbitals is minutely serrated; these bones overlap considerably the upper maxillary when the mouth is shut. The...
Seite 75 - Posterior extremity of the maxillary bone extending to a vertical line drawn across the anterior rim of the pupil. First dorsal anteriorly filiform. Extremities of posterior rays of both the dorsal and anal, projecting beyond the insertion of the caudal. Anal fin shorter than the second dorsal, and not as deep as the the latter is high. Ground color of a uniform rusty red. A black band crosses the eye, through the pupil, and extends across the cheeks. Collected at Fort Steilacoom, Puget Sound.
Seite 165 - When mature, the eggs either fall into the space between the membranes or ovarian pouches, or else remain attached to the ovaries until the embryos issue out of them. We are inclined to think that they drop into the pouches as eggs. At any rate we found very young embryos loosely contained in the ovarian pouches when no trace of the egg membrane could bo seen within the tissues of the ovaries in the shape of a corpus luteum or a graffian vesicle.
Seite 313 - Body fusiform in profile, very compressed ; head comprised four times in the length, the caudal fin excluded. Upper jaw longest ; maxillary curved, extending to a vertical line intersecting the posterior rim of the orbit. Anterior margin of dorsal equidistant between the extremity of the snout and the base of the caudal.
