PROTOMEDEIA WHITE! . 301 



pair of legs are only furnished with a few scattered 

 hairs; the wrist is not longer than the hand, which 

 gradually tapers from the carpal articulation to the ex- 

 tremity, where is attached a short sharp finger. The next 

 two pairs of legs are tolerably long, but terminate in 

 rather short fingers. The last three pairs of legs are 

 damaged, but the thighs are dilated, and taper rather 

 suddenly to the extremity. The last of the caudal 

 appendages were wanting in the only specimen that 

 we have obtained; and the terminal plate is double, 

 differing in this respect from Zaddach's description of 

 P. pilosa, as well as from those exotic species which 

 we had the opportunity of examining through the kind- 

 ness of Mr. Stimpson. 



Of this species, like the preceding, we have received 

 only a single specimen which was taken at Banff, by 

 Mr. Edward ; and which we have named in compliment 

 to Mr. Adam White, the author of a popular History 

 of the British Crustacea, as well as of many valuable 

 Papers on Carcinology published in the Proceedings of 

 the Zoological Society of London.
