Hypoplectrus aberrans Poey, Synopsis, 291, 1868 (Havana)- 

 Hypoplectrus unicolor aberrans, Jordan & Evermann, Fishes of North Amer- 

 ica, 1,193. 



Soft dorsal finely specked with brown (in spirits) ; body cloudy 

 yellowish brown ; the scales behind and above pectoral each with a 

 pearly dot ; a large black spot on caudal peduncle ; black spot in 

 front of eye, surrounded by sky blue, a blue stripe across cheek and 

 around eye, one or two vertical blue stripes behind eye, and several 

 on top of head. 



81. Dules dispilurus (GLintker). Grassy Ground Rock Fish. 



Centropristis dispilurus Giinther, Proc. Zool. Soc. Lond., 1867, 99, (Trini- 

 dad). 



Dules dispilurus, Jordan & Evermann, Fishes of North America, 1,219. 



Several specimens 3i in. long, which according to Mr. Roberts is 

 the maximum size. He also states that in life there are " two dorsal 

 and caudal stripes of white and pink, belly white, pectoral deep red." 

 The inner teeth of both jaws are somewhat depressible, and there 

 are 7 branchiostegals in five of the six specimens. The lower (seventh) 

 branchiostegal is rather small and is wanting in one specimen, leav- 

 ing but six. Apparently the presence of only six branchiostegals 

 cannot distinguish Dules from Prionodes. The caudal is truncate in 

 Dules, lunate in Prionodes. This species is evidently distinct from 

 Dales subligarius and doubtless from Dales aurlga also. It may be 

 that Dales jiaviventris and brasiliensis are synonyms of Dules auriga 

 rather than of Dules dispilurus. In any event we may let the name 

 dispilurus stand pending investigation. 



82. Rypticus saponaceus (Block & Schneider). 



Anthias saponaceus Bloch & Schneider, Syst. Ichth., 310, 1801 (Havana). 

 Rypticus saponaceus, Jordan & Evermann, Fishes of North America, 1,232. 



This is a deeper fish than the following, the depth being equal to 

 or greater than the length of head.
