18. Stegophilus punctatus, sp. n. (Plate XXI. 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 1 14 millim. 



Cauelos. A single specimen.

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 -gug- ; 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 13.5 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 praemaxillary teeth of 

 P. bucTtleyi is clearly quite distinct from that of the species estab- 

 lished 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 

 say, Valenciennes's figure not being executed with sufficient accuracy, 

 and the description merely stating " le bord (des dents) est denticule 

 et comme finement frange."
