large and somewhat flexuous, impinging, when closed, against the posterior 

 projection of the propodos. The 2 anterior pairs of pereiopoda not very much 

 elongated, basal joint somewhat expanded, and nearly as long as the remaining 

 part of the leg. The 3 posterior pairs of pereiopoda successively increasing 

 in length, basal joint of the antepenultimate pair rather broad and obliquely 

 rounded, that of the penultimate pair of a regular oval, that of last pair some- 

 what larger, and having the posterior edge strongly curved. Last pair of 

 uropoda scarcely extending beyond the others, basal part somewhat expanded, 

 terminal joint about same length and cylindrical in form, with 2 strong 

 apical spines and a few slender bristles. Telson very small, somewhat 

 broader than it is long, and transversely truncated at the tip, lateral corners 

 dentiform projecting, and having inside 2 unequal spines. Body more or less 

 densely mottled all over with dark pigmentary spots, giving the animal 

 sometimes a blackish hue. Length of adult female 3 mm, of male about 

 the same. 



Bemarks. This form was first described by the Rev. Mr. Norman 

 under the above name from British specimens, and was subsequently recorded 

 by Boeck from the Norwegian coast. The Ortkopdtme TerscheUingi of Hoek 

 is undoubtedly the same species. On the other hand, that described by 

 M. Bonnier as Microprotopus maculatus must be regarded as specifically 

 distinct, differing, as it does, very conspicuously in the structure of the 

 posterior gnathopoda both in the female and male sexes. It was originally 

 described by M. Chevreux as M. longimanus, and ought to be maintained as 

 a distinct species. 



Occurrence. I have met with this form in several places both on 

 the south and west coasts of Norway, as far as to Bergen. It is generally 

 found in comparatively shallow water, from 2 to 10 fathoms, sandy or 

 muddy bottom. 



Distribution. British Isles (Norman), Kattegat (Meinert), Dutch 



coast (Hoek), coast of France (Chevreux), Azores (Barrois).
