Family CENTROPOMID^. 



140. Centropomus mexicanus Bocourt. 



Specimens of what are apparently referable to this species were taken 

 at Para, Natal, Lake Extrenioz and Lake Papary. The lateral line is usually 

 slightly dusky as in the picture published by Vaillant and Bocourt (Miss. Sci. 

 Mex. 1875, PI. I) except in a large individual (14 inches long) where a 

 dark spot above and below the pore on each scale gives the line a distinctly 

 darker appearance, or in others where it is nearly colorless. 



Centropomus constantinus Jordan and Starks is synonymous with this 

 species. It was separated chiefly on account of its lateral band being color- 

 less, its dorsal spines more slender and shorter, and its body deeper. In all 

 of these characters it falls within the range of variation of the specimens 

 at hand. The type of C. constantinus has a slightly shorter anal spine than 

 the others, but the difference is not of sufficient value to separate the species. 



Doctor Boulenger has united C. mexicanus with C. parallelus Poey, but 

 if the latter was correctly described as having 90 series of scales it seems 

 scarcely probable that it can be the same. In the large numbers of speci- 

 mens of C. mexicanus at hand the variation is only between 68 and 73. 



141. Centropomus undecimalis (Bloch). 



This species is common in Lake Papary, where several specimens were 

 taken. 



Family SERRANID^. 



142. Cephalopholis fulviis (Linnaeus). 



Two specimens from Natal represent both the brown type of color with 

 blue spots (Bodianus fulvus pnnctatus) and the scarlet type with black spots 

 (Bodianus julvus ruber.) 



143. Epinephelus adscensionis (Osbeck). 



Three small examples taken at Natal. 



144. Promicrops guttata (Linnaeus)'. 



One specimen, a foot in length, was taken at Para. As compared with 

 a specimen of similar size from Jamaica the head is a little shorter, and the 

 eye a little larger. The greater length of the head in the Jamaica specimen 

 is all in the postorbital region. 



145. Rypticus coriaceus (Cope). 



Two small specimens were collected at Natal. Dr. Boulenger has 

 placed this species, perhaps correctly, in the synonymy of Rypticus sapo-
