FIG. 1 Synalpheus comatularum. X1.5. 



Fio.j[2. S. brucei: e, eye; ch., small chela with its incurved thumb. X3. Only a single example 

 of S. comatularum and another of S. brucei is figured, so no idea of the variation in 

 extent of pigmentation is shown, but only the type of arrangement. But both the 

 type and variation are alike in the two species, that of S. brucei having rather deeper 

 pigmentation, the bands being wider and the lateral unpigmented areas in the ab- 

 dominal segments being completely enveloped by pigment.
