According to Milne Edwards and Bouvier Anapagurus differs from Spiro- 

 pagurus in the following characters : — 



The chelipeds are very unequal, the right being the larger (the disparity, 

 in adult males, being, according to Henderson, ofien very striking). 



The flagellum of the ist maxillipeds appears to be not articulated. 

 The giU-plates are broad, and not, or hardly, bifid at tip (but this is also 

 the case in Spiropa^urus spiriger). 



The left vas deferens is simply curved, not coiled. 



The 4th and 5th thoracic legs are generally subcheliform. 



Henderson emphasizes the following differences : — 



The right cheliped is much larger than the left : the and and 3rd thoracic 

 legs are long and slender: the left vas deferens is a short, curved, mem- 

 branous organ. 



The members of this genus are for the most part sublittoral, and appear 

 to find their optimum on the European and African side of the North Atlantic 

 from Norway to Cape Verde. Two species are found in the West Indian 

 region, down to 229 fathoms; two of the Eastern North Atlantic species 

 extend into the Western Mediterranean ; one species — a variety of the 

 Eastern Atlantic /4. pnsillus — occurs in Japan ; one species has been reported 

 from the New South Wales littoral ; and finally, a damaged specimen that, 

 I think, can only be referred to this genus, occurs in Mr. Stanley Gardiner's 

 Maldive Islands collection. 



I. Anapagurus sp. 



The single specimen has a carapace not quite 4 millim. long, and has 

 lost all its large appendages, except one ambulatory leg. The left vas defer- 

 ens is a stout, soft, simply-curved tube of considerable length. The single
