FAMILY CLINIDAE — SCHULTZ 297 



Sexes alike in body and fin proportions, differing only in color; male 

 with a small conical urogenital papilla, female with a broader, rugose 

 urogenital papilla; size at maturity small, largest adult 21.4 mm. 

 standard length, smallest mature specimen 15.1 mm. standard length. 



Color in alcohol. — Males with body ground color translucent pinlc, 

 throat and lower parts of head dark brown to black, this coloration re- 

 stricted to the portion of the head below the level of the lower margin 

 of the orbit; the dark coloration of the head is continued onto the 

 pectoral base as a dark triangle, the apex of which encroaches on a few 

 of the middle pectoral rays; and all unpaired fins clear. Females and 

 juvenile males with entire body a clear pink, no dark pigment present. 



Remarks. — Helcogramma chica is in many respects quite similar to 

 Helcogramma fuscipectoris (Fowler) {= Enneapterygius fuscipectoris 

 Fowler, Proc. Acad. Nat. Sci. Philadelphia, vol. 98, 1946, p. 186, fig. 

 50-51). Enneapterygius personatus Fowler (ibid. p. 185, fig. 48-49) 

 is here regarded as a synonym of Helcogramma fuscipectoris (Fowler). 

 I have examined the holotypes of both of Fowler's species, and have 

 the paratypes before me. H. chica agrees remarkably well with H. 

 fuscipectoris in body proportions, fin ray formula, and certain details 

 of coloration. It differs from that species, however, in several im- 

 portant respects: H. fuscipectoris has a well developed orbital tentacle, 

 the unpaired fins and the sides are dusted with melanophores which 

 tend to be arranged in faint bars, and there are three scales between 

 the lateral line and the third spine of the second dorsal. Helcogramma 

 chica is distinguished from its Marshall Island congener, FI. capidata 

 in the discussion of that species. 



The trivial name of this form, which is taken from the Spanish ad- 

 jective meaning httle, refers to the small size at maturity.
