Branchiostoma longipes, Newport, Tr. Linn.Soc. xix. p. 411. 



The British Museum lias a specimen of this species ticketed 

 merely W. Indies. Meinert, however, recorded it from St. Croix 

 and St. Kitts. It also occurs commonly in many parts of the 

 Oriental Region. It may be readily recognized from the fol- 

 lowing species by the presence of spines upon the femora of the 

 anal legs.

This species is unknown to me. Meinert has recorded it from 

 Kingston in Jamaica. It was described by its original authors 

 from Georgia in N. America. 



In this species the femora of the anal legs are said to be 

 unarmed.
