Two specimens, 4J in. long. No. 4,963, L. S. Jr. Univ. Mus. 



The specimens here described differ from the description of punctus 

 Poey, in having but 6 branchiostegals, and in having the yellow dor- 

 sal margin restricted to the soft portion. The species is very close to 

 Chromis marginatus. Compared with a specimen of this species 

 from Bahia, Chromis multilineatus differs in the following respects: 

 body more elongate, a greater number of last rays of dorsal yellow, 

 a distinct bright yellow spot present behind dorsal. 



Chromis marginatus has the depth 2 2 in length, there is but one 

 pale or yellow ray in the dorsal, and there is no yellow spot at the 

 base. The axil is jet-black in both, the color encroaching on the 

 upper base of the pectoral. 



Chromis atrilohatus Gill, from the Pacific coast, is also very simi- 

 lar, but in this species there is a black bar across base of pectoral.
