included specimens of A. vittatus, which is relatively common in the area of his 

 study. , ,; . 



Thatcher and Boeger (1984) described a copepod that parasitizes the nasal 

 capsule of A. brevifilis. 



Comments 



Boeseman (1972) reported on two specimens in Leiden (RMNH 2975) and 

 concluded that the larger of the two (240 mm SL) was the specimen on which 

 Valenciennes based his description, and thus represents the holotype. There was no 

 reference to the smaller specimen in the original description. It was presumably 

 retained by C. J. Temminick, former director of RMNH, in the event the holotype ^ 

 was lost. Eigenmann (1912) stated that the figure by Bleeker (1864) was of the 

 smaller specimen, a conclusion apparently based on pigmentation of the fins, - • 

 Boeseman (1972) also noted an apparent error in the type locality, commonly cited 

 as Cayenne (French Guiana). The specimens were collected by H. H. Dieperink, 

 presumably in the vicinity of Paramaribo, Surinam. Neither specimen was examined 

 in the present study. [ ;''
