similar structure, except tliat the carpal lobe is somewhat narrower, and that 

 the propodos is a little broader in proportion to its length; those in male 

 very unlike those in female, and rather powerfully developed, carpus short 

 and produced below to a narrow setiferoiis lobe, propodos extremely large 

 nearly equalling half the length of the leg, and oblong oval in form, palm 

 occupying almost the whole lower edge, being miniitely denticulated and 

 expanded in front to a somewhat irregular, densely setiferous lobe, rounded 

 at the tip, dactylus very strong and somewhat flexuous. The 2 anterior 

 pairs of pereiopoda with the basal joint pronouncedly lamellar, with the 

 anterior edge boldly curved below, meral joint expanded in front to a broadly 

 rounded lobe, dactylus terminating in a blunt point. The 3 posterior pairs 

 of pereiopoda moderately strong, with the propodal joint armed on the anterior 

 edge with a row of small spines, basal joint of antepenultimate pair rather 

 broad and obliquely rounded, that of the last 2 pairs oblong oval in form- 

 Last pair of uropoda with the outer ramus minutely denticulate on the 

 upper edge and armed at the tip with 2 strong, recurved hooks, inner ramus 

 broader than the outer, and obliquely tnincated at the tip, which carries 

 several slender bx'istles and 2 small spines at the lower corner. Telson nearly 

 twice as broad as it is long, and having on either side of the angixlarly 

 produced tip a small tuberculiform projection. Body, according to Sp. Bate, 

 of a yellowish or fawn coloiir, with a few red marks at the origin of the 

 legs. Length of adult female 8 mm, of male aboiit the same. 



Remarks. — There cannot be any doubt that the above-described form 

 is that so named by Sp. Bate. The latter author only examined the male 

 sex, but the female has subsequently been described by the Rev. Mr. Stebbing. 

 The Aniphithoc grandimana of Boeck is without any doubt the male of this 

 species. The strixcture of the gnathopoda in the 2 sexes will suffice to 

 recognize at once this form from the 2 preceding ones. 



Occurrence. — I have only seen a few specimens of this form, which 

 were collected, many years ago, at Apelveer, Namdal, in comparatively 

 shallow water, among algae. Boeck records the species from Farsund, south 

 coast of Norway. 



Distribution. — British Isles (Sp. Bate), coast of France (Chevreux), 

 Azores (Barrels).
