South African Crustacea. 75 



reddish, still after long preservation in spirit. In general appearance 

 there is an extraordinary resemblance between the specimen from 

 South Africa and the figure which Dr. Giles gives of his species 

 from the Bay of Bengal. Besides the want of eyes, however, that 

 species offers another distinction shown in a detail figure and clearly 

 noted in the description, namely, that in the third uropods "the 

 inner ramus is considerably shorter than the first joint of the outer." 

 In our species the inner ramus is nearly as long as the first joint of 

 the outer. In regard to the mouth-organs of the Indian species, some 

 of the detail figures and statements must be attributed to the use of 

 inadequate apparatus. The palp of the mandible, for example, is 

 said to be two-jointed. The palp of the first maxilla is figured as 

 one-jointed. It is not easy to believe that such differences could 

 coexist with the remarkable likeness which the head and peraeopods 

 show to those of our species. Stimpson's description of his Japanese 

 species is very brief, but contains one noteworthy expression "rami 

 of the posterior caudal styles unequal, the outer ones long, three- 

 jointed " with which I may compare my own preliminary note on 

 the South African specimen, uropod 3, outer branch much longer 

 than inner, the spination giving it an almost three-jointed appear- 

 ance. Stimpson gives white as the colour of his species, and Giles 

 describes his as of a uniformly dirty-white colour. The African 

 specimen attracted attention by the conspicuous red of some parts, 

 while others were white. But this is not necessarily differential, if 

 we consider the account given by Dr. Giles of his species Para- 

 pleustes pictus, in which the red and white are variously distributed 

 in different specimens, which were " found crawling upon a Pen- 

 natula, the pink and white colours of which are almost exactly 

 imitated in the amphipod " (J. Asiat. Soc. Bengal, vol. lix., p. 71). 



PONTHARPINIA STIMPSONI, n. sp. 



Plate XXXVII. 



Head elongate, rostral part broad till near the apex, which is 

 drawn out to a very fine point curving downwards. Of the peraeon 

 segments the second is the shortest. First side-plate with rounded 

 front produced forward, fourth much the largest. Third pleon seg- 

 ment with postero-lateral corners rounded and a row of setae carried 

 obliquely from the corners almost across the surface ; fifth and sixth 

 segments small. 



Eyes small, irregularly oval, dark red, placed wide apart just be- 

 hind the post-antennal corners. First antennae with first joint large,
