pointed out as separating the two, so I use the oldest name for the spe- 

 cies. Gerres ejnbryx is known from a single very large specimen, 

 the size of which may well account for the slightly longer pectoral. 

 There seems to be no other difference between the two. 



57. Cynoscion jamaicensis (Vaillant & Bocourt). 

 Maceio. 



Two specimens, which agree entirely with those reported on by 

 Jordan and Rutter from Jamacia.^ 



The species is evidently distinct from C. obliqicatus^ having a greater 

 depth, a larger eye, a longer snout, a shorter anal fin, and biconcave 

 caudal. Its relationship with C. nothus is much closer. I have no 

 specimens of the latter at hand for comparison, but from current de- 

 scription can find nothing to distinguish C. jajnaicensis but a some- 

 what longer head and deeper body. The anal may also be shorter. 

 In C. notJnis^ the lateral line becomes straight under the seventh ray 

 of the second dorsal, not under the seventh dorsal spine, as stated by 

 Jordan and Eigenmann'^ and by Jordan and Evermann.' C acoupa 

 is certainly different, as it has very different proportions and smal- 

 ler fins. 



58. Cynoscion virescens Cuvier & Valenciennes. 



A fine specimen, 50 mm. long, agrees perfectly with Steindachner's 

 account of C. microps. Steindachner is correct in enumerating 55 

 enlarged scales in the lateral line. Our specimen has 57. It is not 

 clear what can have led Jordan and Eigenmann* and later Jordan and 

 Evermann* to state that the lateral line contains 80 pores. 



59. Menticirrus martinicensis (Cuvier & Valenciennes). 

 Maceio. 



60. Eupomacentrus fuscus (Cuvier & Valenciennes). 

 Mamanguape. Maceio ; Rio Goyanna. 



This is certainly identical with E. diencceus Jordan and Rutter. 

 The latter is based on very dark specimens from Jamaica. The dark 

 pigment thus involves the whole axil of the pectorals, appearing in a 

 dark spot below as well as above the base of the fin. In one of our 

 Brazilian specimens, the dark color almost reaches the lower edge of 

 the axil. The ventral fins are subject to much variation in this species,
