STEMMIULUS INSULANUS Chamberlin 

 Sfemmiulus insulanus Chamberlin, Bull. Mus. Comp. ZooL, vol. 62, p. 178, 1918.

Fig. ^.—Stcmmiulus insxilamis. a, gonopods, anterior view; b, gonopods, 

 posterior view. 



All the above specimens are smaller than Chamberlin's type, which 

 was a male. A 14-millimeter male and a female of the same length 

 were the largest specimens collected by the writer. The living color 

 notes state that the head, the first three segments, and the anal seg- 

 ment are light red, with the posterior half of segment 3 and succeeding 

 segments dark colored. 



The gonopods are shown in figure 4, a and h.
