South America or West Indies. Obs. About the size of C. enops, but distinguished by its red throat and green under wing-coverts. 4. O n an undescribed Pimelepterus from Port Jackson. By J. D O U G L A S OGILBY, Department of Fishes, Aust. Mus. Sydney. (Communicated by F. D A Y , CLE., F.Z.S.). [Received November 1, 1886.] PIMELEPTERUS MERIDIONALIS, sp. nov. B. vii. D. 10-11/12. A. 3/10. V. 1/5. P. 17. C. 17. L. lat- 57-59. L. tr. 10/19. CEBC. pyl. ca. 460. Vert. 11/15. Length of head from 485 to 5*15, of caudal fin from 4*66 to 5*00, of pectoral fins from 7*00 to 7*20, height of body from 3 00 to 3*20 in the total length. Eyes : diameter from 4*00 to 4*50 in the length of the head, from 1*60 to 1*75 in that of the snout, and from 2*00 to 2*30 in the convex interorbital space. Body oblong, compressed ; a transverse rounded protuberance in front of the eyes. Cleft of mouth small and transverse ; upper jaw rather the longer ; the maxilla reaches to below the anterior margin of the orbit. Pre-, sub-, and interopercles entire. Teeth: a single row of strong curved conical teeth in each jaw, the horizontal portion of which is of equal length with the vertical ; behind these rows are narrow bands of similar but much smaller teeth, which probably are intended to finally replace the outer row ; vomer, palatines, and tongue densely crowded with minute teeth \ Fins : dorsal spines of moderate strength, increasing in length to the seventh, which is about one half the length of the head, and much longer than the rays of the dorsal, though only equal to the first anal ray. Pectorals rounded, rather longer than the ventrals, and from two thirds to three fourths the length of the head. Third anal spine longest and strongest; caudal emarginate. Scales feebly ctenoid, extending in front of the eyes; much smaller on the head; 18 between the bases of the ventrals and the lateral line, and 8 between that and the base of the sixth dorsal spine ; those below the lateral line larger than those above it. Pseudobranchice well developed. Gill-rakers 20. Colours dull brownish grey, with a silvery shade below; upper part of head darkest; all the fins dark. Irides a mixture of orange and silver. 1 In connection with tbe dentition of Pimelepterus, I m a y mention that Girella tricuspidata has a small patch of palatine teeth. Dr. Giinther (Cat. i. p. 427) states that "in one species there is a short series of palatine teeth," but he omits mentioning which species possesses this series. |
