2 68 PAPERS FROM TORTUGAS LABORATORY vol. xxxiv 



In June the gonads of the males are small, but characteristically developed; 

 those of the female have few or no visibly differentiated eggs. W. H. L. 



The collection contains many specimens, ranging in length from 26 to 82 mm. 

 The following proportions and enumerations are based on 2 specimens 51 and 82 

 mm. long: Head 3.8, 3.9; depth 4.3, 4.2. Eye in head 3.0, 4.0; snout 3.5, 4.2; max- 

 illary 2.5, 2.1; pectoral 1.2, 1.3. D. XII,i7, XIII,i8; A. 11,19, II,2o; P. 14 (4 speci- 

 mens counted).

 Blennius microstomas Poey, Memorias, vol. 2, i860, p. 288 — Cuba. 



Common toward the outer face of Bird Key reef, and the young have been 

 taken along rocky shores of Loggerhead Key. Its pectorals are stronger than 

 those of Blennius marmoreus and it leaps about much more actively. 



The identification of B. microstomas with B. cristatus rests on Poey's descrip- 

 tion of the type, which is sufficient to show what fish he had. The fin formulas 

 he gave (D. XII, 15; A. 1,17) correspond to those of Tortugas specimens of B. 

 cristatus (D. XII,i5 or 16; A. II,i6 or 17), allowance being made for the fact that 

 no blenny has normally a single anal spine. Poey either overlooked the hidden 

 first spine of the female, or counted the 2d spine of the male as an articulated 

 ray. The structure of the pectoral is the same in his type specimen and in B. 

 cristatus; the coloration agrees; and due mention is made of the longitudinal 

 series of filaments on the nape. Nothing is said regarding posterior canines, and 

 indeed at the size attained by his type there is little to say, as these teeth are as 

 yet not fully or not at all developed. W. H. L. 



Although reported as common in certain places locally, only 6 specimens, 35 to 

 68 mm. long, are included in the collection. A series of cirri on the median ridge 

 of the nape distinguishes this species from other blennies in the collection. The 

 following proportions and enumerations are based on 2 specimens, 35 and 68 

 mm. long: Head 3.6, 3.8; depth 4.25, 4.0. Eye in head 2.7, 3.4; snout 4.3, 3.75; 

 maxillary 2.6, 2.5; pectoral 1.13, 1.15. D. XII, 15, XIL16; A. 11,17, ^ l 7'i P- x 4> M-

Not common, though several were sometimes found about a single one of the 

 great Orbicella heads, to which it appeared to be confined. It is very active and 

 not easy to catch, but may be trapped with a large test tube, or with a glass jar 

 baited with a broken sea urchin. Empty, gaping bivalve shells seem to be attrac- 

 tive shelters. From one shell 0/ Spondylus with one valve fixed to the roof of an
