Through the kindness of Major H. N. Benett, R. M. I., Commandant of H. M. Island Ascension in the tropical Atlantic, we have had the pleasure of examining a topotypical example of the trigger fish, Batistes vetula Linnaeus.

. Copeia. Ichthyology; Herpetology. New York, January 24, 1917. No. 39. Published to advance the Science of cold-blooded vertebrates A BALISTES VETULA TOPOTYPE FROM ASCENSION. Through the kindness of Major H. N. Benett, R. M. I., Commandant of H. M. Island Ascension in the tropical Atlantic, we have had the pleasure of examining a topotypical example of the trigger fish, Batistes vetula Linnaeus. Reference to this fish was made by the writers in 1914, in connection with the description of a new race of the species from Trini- dad Islet in latitude 20 south (Bull. Amer. Mus. Nat. Hist., Vol. XXXIII, pp. 265-26(3). At that time we knew of no specimen in America of Batistes vetula from the type locality, and in describing the sub- species trinitatis, which obviously differed from the West Indian form, we stated that the former might possibly prove to be identical with Linnaeus's B. ve- tula of Ascension, in which case a new name should be sought for the well-known representative of West Indian waters. Major Benett generously agreed to assist in settling the problem, and in due course an adult specimen preserved in formalin has reached us, and has been catalogued as number 553 in the col- lection of the Brooklyn Museum. We have compared the Ascension Island fish with the tvpe of trinitatis which it almost exactly equals in size (being 380 mm. long to base of caudal) as follows: Head, in length to base of caudal; depth, ; thickness of body, in head. Head bluntly pointed, dorsal and ventral outlines similarly.
