This attractive species has been amply illustrated by the 

 three authors above mentioned, and also by Lo Bianco and 

 Eiggio, whose figures I have not seen. The length appears rarely 

 to exceed 30 mm., but Kemp mentions a specimen of 38 mm. 

 The South African specimen is 33'5 mm. long. After 16 years 

 in formalin there are still spots of a rich blue on the first four 

 pairs of peraeopods, some less vivid on the first antennae, pur- 

 plish on the stalks of the golden yellow eyes, with the mouth 

 organs darkly red and the carapace covering a lighter red sub- 

 stance, its own rostrum and probably all the rest of it being 

 pellucid.
