REPORT OF THE DIRECTOR I918 137 



Gampsonyx brasilicus sp. n. 



The head is absent. The thoracic somites are niimerous and 

 appear to be from eight and more, very narrow and bandlike, all the 

 posterior members bearing a median pustule. The abdomen consists 

 of six broader somites with lateral triangular posteriorly directed 

 extensions, those on the ultimate joint being distinctly leaf-shaped. 

 The telson is narrow and the stylets in two pairs, the outer being the 

 longer.
