NO. 7 GINSBURG : NEW SPECIES OF GOBIOID FISHES 117 



throat or ventral aspect of belly; scales on middle of body extending 

 to within a short distance of base of pectoral; anterior boundary of 

 scales marked by a line passing approximately from origin of first dorsal 

 to upper angle of pectoral base; scales along middle part of body, pos- 

 teriorly, ctenoid ; anterior scales under base of second dorsal, and those 

 near profiles, cycloid (most scales missing in specimens examined and 

 description of squamation possibly subject to correction). First dorsal 

 with 7 flexible spines (in all 4 specimens examined), rather high, but 

 none notably filamentous, the fourth reaching base of second or third 

 dorsal ray. Second dorsal rays usually 12 (in 3), sometimes 11 (in 1) ; 

 anal rays 11 (in all 4) ; posterior dorsal rays extending a little beyond 

 a vertical through end of hj^pural in 2 males 41-43 mm, those of anal 

 just reaching that vertical or slightly beyond in the same two males; 

 those of both fins just about reaching that vertical in a specimen 35 

 mm, and falling a little short in a male 28 mm. Pectoral rays 19 (in 

 1 ) or 20 (in 3), all connected by an interspinal membrane, the fin 

 rather long, the longest rays reaching a vertical through base of third 

 to fifth ray of second dorsal. Ventrals united, interspinal membrane 

 rather well developed, its posterior margin with notably pronounced 

 fimbriae; posterior end of fin reaching anus or falling a little short. 

 Caudal rather long, equal to or a little less than half the standard 

 length in the large males. Anal papillae of male rather short and pointed. 

 A longitudinal, rather narrow, dark streak slightly below a median 

 line, approximately from base of pectoral to under origin of second 

 dorsal; a similar less well marked, interrupted and parallel streak a 

 little above a median line; (a longitudinal series of four rather diffuse 

 blotches on the 28 mm specimen, the first at posterior end of and con- 

 fluent with lower dark streak, the last at base of caudal ; only the last 

 blotch perceptible in the larger specimens examined, but these specimens 

 probably faded) ; two spots on base of caudal, one below the other, 

 more or less confluent, and more or less also confluent with the last 

 spot — in the longitudinal series of four spots — on the base of the caudal ; 

 a small oval spot on fleshy base of pectoral, a more diffuse, transverse, 

 rather arched shaded area on fin, at its base; upper part of caudal with 

 longitudinal rows of narrow elongate dark spots (in one specimen, the 

 dark spots very intense, alternated with whitish spots, and with a 

 whitish submarginal band ; this pronounced development of color proba- 

 bly showing a sexually ripe male), lower part dusky (dorsals and anal 

 more or less injured and color cannot be described).
