The anterior gonopods are leaf-like in form, and, being 

 convex posteriorly, their lateral edges wrap round and protect 

 the anterior branch of the posterior gonopods somewhat 



The posterior gonopods consist of a foliaceous anterior 

 branch and a subtrapezoidal posterior portion. 



The anterior branch consists of three parts — a, b, and c — 

 which are very distinct and characteristic; a is finger-shaped 

 and is the longest, standing out well beyond the others ; the

 more nearly to a. 



The structure of the posterior gonopod is clearly seen in 

 fig. 8, which represents the inner view of the gonopods both 

 anterior and posterior of one side. In this case the appendages 

 have been flattened out somewhat to show the separate parts 

 of each. The most prominent part of the posterior portion of 

 the posterior gonopod is the hooked piece, d, which is sparsely 

 plamous at the tip, while a noticeable feature is the flngellum,
