2531. SICYDIUM VINCENTE, Jordan & Evermann, new species. 



Another species of Sicydium or of some related genus is thus mentioned 

 by Dr. Eigenmann : " Mr. Samuel Garnian collected several hundred speci- 

 mens of this species at Kingston, St. Vincent. Most of these specimens 

 are less than an inch in length, the longest 1 inches ; they differ consid- 

 erably in coloration from the adult; most are entirely naked, a few of 

 those examined having scales only on the posterior part of the body. 

 Caudal deeply emargmate. There are traces of about 7 dark vertical 

 bars ; a black bar at base of pectoral ; dorsals with several series of black 

 spots; an H-shaped figure on base of caudal, a black bar on the posterior 

 half of caudal fin; belly and lower part of body plain; everywhere else 

 with black points. The specimens collected by Mr. Garman may be the 

 types of a new species. No large specimens were collected at the Island 

 of St. Vincent. Specimens 1 inches in. length from Hayti have the fins 

 plain and a series of blotches along the middle of the posterior part of 

 the body; the body, except the belly, is entirely covered with scales which 

 are plainly ctenoid." (Eigenmann.) (Named for St. Vincent.)

 Sicya, JORDAN & EVERMANN, Check-List Fishes, 456, 1896 (gymnogaster). 



This genus is closely allied to Sicydium, agreeing closely with the latter 

 in external characters and in the absence of larger teeth in front of lower 

 jaw; it differs chiefly in the form of the upper teeth which are curved, 

 tricuspid, and trident-shaped, the middle cusp either permanent (Cotylo- 

 pus) or else worn away leaving the tooth apparently bicuspid (Sicya).

Head 4i to 5; depth 5| to 6. D. VI-I, 10; A. I, 10; scales 60 to 64; 

 eye 6 in head, twice in interorbital space. Teeth in the upper jaw tri- 

 cuspid, the middle cusp, which is situated at the anterior end of tooth, is 

 very soft and soon becomes worn away. A double or treble row of small 

 papilla on the gum beneath the upper lip, without a larger median 

 papilla; upper lip with a very slight median notch; maxillas containing 

 an angle of about 75 ; horizontal teeth more or less inconspicuous. Scales 

 strongly ctenoid; neck and belly naked. Length of pectoral greater than
