Show 1887.] BY MR. C. BUCKLEY IN EASTERN ECUADOR. 279 18. STEGOPHILUS PUNCTATUS, sp. n. (Plate XXL fig. 4.) D. 8. A. 7. P. 6. V. 5. Closely allied to S. macrops, Stdr. Head as long as broad ; its length is* contained six and a half times in the total, the depth of the body nearly nine times. Eye large, covered with skin ; its diameter equals the length of the snout and is contained four times in the length of the head. Barbel shorter than the eye. Anal behind the dorsal, the origin of which is nearly midway between the occiput and the extremity of the caudal. Latter fin emarginate. Pale brown above, with numerous small brown spots; a lateral series of large rounded purplish-brown spots ; dorsal and caudal brown-spotted. Total length 114 millim. Canelos. A single specimen. CHARACINIDJE. 19. CURIMATUS DOBULA, Gthr. Curimatus dobula, Giinth. Proc. Zool. Soc. 1868, p. 243. Curimatus nasus, Steind. Sitzungsb. Ak. Wien, lxxxvi. i. 1882, p. 80, pl. v. fig. 2. Canelos. 20. PARODON BUCKLEYI, sp. n. (Plate XXIII. fig. 1.) D. 12. A. 9. P. 17. V. 8. L. lat. 37. L. transv. 9. Dental formula ?=S=-2 ; prsemaxillary teeth fringed rather than denticulated, each with about twenty fringes. The height of the body is not quite one fourth of the total length (without caudal), the length of the head one fifth. The height of the dorsal a little exceeds the length of the head ; its origin is nearer the adipose fin than the end of the snout, and falls above the thirteenth scale of the lateral line. A length of six scales separates the extremity of the pectoral from the base of the ventral, which falls below the middle of the dorsal ; ventrals extending slightly beyond the vent. Upper half pale brownish, lower yellowish, separated by a greyish band ; a brown band along each side of the back ; fins unspotted. Total length 135 millim. A single specimen from Canelos. This being the first specimen of the genus Parodon received by the British Museum, the characters enumerated in the following tabular synopsis of the species hitherto described are merely the result of^ compilation. The shape of the premaxillary teeth of P bucldeyi is clearly quite distinct from that of the species established by Kner and by Reinhardt, who describe and figure each tooth with about ten or twelve denticles. Whether the new species differs in this respect from the type of the genus 1 am not able to saV Valenciennes's figure not being executed with sufficient accuracy, and the description merely stating " le bord (des dents) est denticule et comme finement frange." |
