Fig. 13. — Chldmy(W&Uicep&:. Jenkins, new species. Type. 
of ventral 2 in head; basal membrane with a well-developed lobe on each side; scales ctenoid, covering 
body and top and sides of head; those on posterior part of body and on caudal peduncle hut little 
enlarged; those on head smaller than body scales. 
Color in alcohol, plain chestnut brown, pale below; a few darker mottlings on side of body; ventral 
and pectoral fins dusky brown, ventral pale. 
This description is based on a single specimen, 1.5 inches long, taken by me in the coral rocks on
