Argyropelecus caninus Garman, Mem. Mus. Comp. Zool., vol. 24, p. 235, 1899 

 (type locality, Indian Ocean. The type of A. caninus Garman, was photo- 

 graphed by Harvard University through the kindness of Mrs. M. M. Dick, 

 and the prints show the holotype to be badly damaged; preopercular spines 

 are lacking, as is the rear postabdominal spine, the base of which has a ragged 

 edge, indicating that it was broken off. There is little doubt that A. caninus 

 is a synonym of A. aculeatus).
