Show 1894.] OPHIDIA O F TRINIDAD, B. W . I. 517 BOTHROPS ATROX. Found only in swampy places. It ascends a short distance little bushes 5 feet or so from the ground. B. atrox is very fierce, . and sometimes ejects its poison a considerable distance. One which was being teased with a stick ejected its poison in this way. It fell on the face of a woman some twelve feet off. It is rather more active than tbe Lachesis muta and bites more readily. The largest specimens we have seen were about 6 feet long. The B. atrox is locally called " Mapepire Balsain," which is said to mean striped. It is called in some localities " Valsain," which no doubt means dancing (from the French), an allusion to the circling motion when in the attitude of defence, which all vipers exhibit. A Preliminary List of the Ophidia of Trinidad, B. W. I. NOTE.-The snakes found by us in Trinidad are marked with an asterisk; where we have not seen the snakes ourselves the name of the recorder is given. The names of authorities given within square brackets after the species are those of the naturalists to whose kindness we are indebted for the determinations of the species. OPHIDIA. TTPHLOPIDJE. *1.
