SYNALPHEUS GOODEI, new species. 



The frontal margin very forcibly suggests that of the preceding 

 species; tlie rostrum is quite a little longer than the lateral spines, 

 and the latter are more completely triangular. 



The articles of the antennule have as proportions, 2.3, 1.2, 1, the 

 antennule being 5 times as long as wide ; the basicerite of the antenna 

 has its superior angle somewhat sharp; its lateral spine reaches the 

 extremity of the median antennular article.

The scaphocerite always possesses a scale, which is of the same 

 dimensions in both sexes, and often reaches the middle of the distal 

 antennular article; the lateral spine is as in the preceding species. 



The carpocerite is 5.2 times (in the young) to 5.7 to 6 times longer 

 than wide.
