1894.] OPHIDIA OP THINIDAU, B. W. I. 517 



BOTHEOPS 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 the Lacliesis 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.

 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
