156 FISTIES FROM GlIAYMAS KVERMANN AND JENKINS. 



Mouth small, horizontal, maxillary short, just reaching vertical of 

 anterior border of eye; each Jaw with a single series of close-set in- 

 cisors, about twenty-six in number. 



Dorsal fin long, its spines strong, depressible in a groove, the lifth 

 to seventh longest, about 2-^ in head; the soft portion rather lower, its 

 last rays about 3.^ in liead. 



Anal s])ines short, the second about 42 in head ; soft anal high, its 

 anterior rays being longest and more than equaling half of head; the 

 posterior rays of anal are contained 3^ times in head, and thus equal 

 the last rays of the dorsal ; caudal fin widoly forked ; caudal, pectorals, 

 and ventrals well scaled at the base, while the soft parts of the dorsal 

 and anal are densely scaled throughout. Scales rather large — sixty 

 in lateral line — except on the fins, where they are very small, and 

 about the head, where they are small and much crowded; the snout is 

 naked. 



C'olor in alcohol not noticeably different from that of K. analogns. 



This species is closely related to K. analo<jns (Ciill), from which it ap- 

 pears to differ in the larger scales, fewer scales in the lateral line, much, 

 higher anal fin, wider interorbital space, and more blunt snout. 



It does not agree with Peters's description as to number of teeth in- 

 each jaw (Peters giving thirty eight while our specimen has but twenty- 

 six), the width of the interorbital and in the fin formula', but these dis- 

 crei>ancies may be due to errors of observation or copying. 



At our request Dr. F. Hilgendorf recently exannned Peters's types 

 and we are indebted to him for the following note: "Schuppen iiber- 

 L. 1, zJihle ich G4-GC und ausserdem etwa 10 kleinere auf den Schwanz- 

 rtosse. * * * Die Hiihe des ersten weichen Strahles der Analis be- 

 trjlgt 38""". Die Basis-Liinge der gauzeu Flosse ist 08"""." 



This, of course, shows tiiat Peters's description is not accurate. We- 

 obtained but one specimen.
