Faxon, in his stalk-eyed Crustacea of the Albatross (Mem. Mus. 

 Comp. Zool., vol. 18, p. 101, pi. 26,tig. I, la, 1895), describes a 

 var- occidentalis. Milne-Edwards and Bouvier notice several 

 variations of their var. concolor, the form with which the South 

 African specimens should be identified, \i a varietal name is 

 necessary. The distinctions drawn by the French authors 

 between the typical form, and the var. concolor refer to the 

 antennae, the mandibles and the trunk legs. The variety has 

 sliarp denticles on the ventral surface of the third and fourth 

 joints of the chelipeds, where the type is almiost smooth. In the 

 African specimens the third joint is almost smooth, the fourth 

 and fifth jomts have rows of rather sharp little tubercles ; the 

 filth joint is almost cylindrical as in concolor rather than obtusely 

 angled al:)Ove as in the type- A dissected specimen has the 

 cutting edge of the mandible divided into ten teeth, and the walk- 

 ing legs have ten spines on the concave margin of the finger, 

 characters which are used to distinguish concolor from the typical 

 form, which has twelve teeth to the mandibular edge and twelve 

 spines on the finger margm. The fingers of the chelipeds are 

 liairy at the extremity, but in this respect not so densely and 

 iDcautifully ornamented as the last two joints of the third maxilli- 

 peds.

MACRURA GENUINA. 



Under the title of " Macrura Astacides," Alcock in his " De- 

 scriptive Catalogue of the Indian Deep-Sea Crustacea, Decapoda 

 Macrura and Anomala," 1901, has recently given a synopsis of 

 the families Nephropsidse, Eryonidae, Palinuridse. Scylkridae. 

 Axiidae, and Callianassidse. As these include all the families of 

 genuine Macrura with which we are here concerned, it will be 

 sufficient to refer the reader to the work mentioned- 



Fam.: Nephropsidae.
