of short hairs on their upper sides in the male, which are wanting 

 in the female. (The eyes are larger in the male.) The flagellum 

 of the lower antennae has long upward-directed setae at the ex- 

 tremities of alternate joints in the female, which do not exist 

 in the male. The first pair of gnathopoda are shorter in the 

 male, with but few hairs near the top ; they are as long as the 

 basis of the second pair of gnathopoda in the female, slender, 

 flexible, with long hairs on the anterior margin, and shorter 

 curved hairs at the distal extremity. The coxae of the second 

 pair of gnathopoda are much higher in the female. The first 

 two pairs of pereiopoda have the carpus and propodos fringed 

 with long hairs at the posterior margin ; these hairs are wanting 

 in the female.

XXXII. — On the Fresh- and Salt-ivater Rhizopoda of England 

 and India. By II. J. Cartek, P. U.S. &c. 



[Continued from vol. xiii. p. 36.] 

 [Plate XII.] 

 In my last communication on the Rhizopoda of England and 

 India, I ended with the mention of the new genus and species 

 Acanthocystis turfacea (Annals, vol. xii. p. 263), the magnified 

 view of the spine of which (vol. xiii. pi. 2. fig. 25 i) should not 

 be tapering in the shaft, as therein represented, but of the same 

 size throughout as at the bifid extremity. (See those round the 

 entire figure.) Will the reader be pleased to make the correc- 

 tion? 



Just preceding the mention of Acanthocystis allusion is made 

 to Actinophrys oculata as having been in company with A. 

 Eichhornii in " fresh water." This is also a mistake ; for I find by 

 my notes that this species was found in another basin, and one 

 which contained salt water. Further, I intimated my intention 

 to write more on A. oculata hereafter; so we will now return 

 to it.
