H. sexpes, Stebbing, No. 7058, sent from the Cape by Dr. 

 Pe'ringuey, but with locality marked as doubtful. The speci- 

 men is a female, with carapace measuring 9 mm. in length by 

 14 mm. in breadth. The emargination of the truncate front is 

 just perceptible. The short eyestalks, thickest at the base, are 

 not immovable, in this respect differing from those of Alcock's 

 Lambdophallus sexpes. The flagella of the slender second antennae 

 are 11-jointed. The characters of the mouth organs will be suffi- 

 ciently seen from the figures. In the second maxillipeds the 

 attachment of the terminal joint of the endopod to the middle 

 of the preceding joint may be noticed. In the third maxillipeds 

 the terminal joint is elongate, answering to de Haan's epithet 

 producti, although his figure gives quite a different impression. 

 The right cheliped is missing ; the fingers of the left are not short 

 as in de Haan's description. The other perseopods agree with de 

 Haan's account, and also with Miers's description and figures of his 

 Thaumastoplax anomalipes. De Haan states that the second [first 

 ambulatory] legs are shorter than those which follow. Miers 

 misunderstood him to be speaking of the second ambulatory legs 

 or third peraeopods. By its dimensions and general character, 

 ncluding eyes, antennas, and other details, Miers's species would be 

 identical with the present, were it not for the very different third 

 maxillipeds, the figure of which is very unconvincing. The third 

 and fourth, or the third, fourth, and fifth segments of the pleon in 

 the males of this genus are coalesced ; in the female of the species 

 here described all seven segments are distinct, the first two the 

 shortest, the third and fourth the broadest, the sixth and seventh 

 the longest. The four pairs of pleopods, attached to the second, 

 third, fourth, and fifth segments respectively, have a long, slender 

 exopod, densely fringed with long plumose setae, and a 6- jointed 

 endopod, strongly geniculate between the long first joint and the 

 much shorter second, all the joints carrying subapical tufts of long 

 simple setae.
