A specimen taken in the Trondbjemsfjord, at Skjorn, exhibited a yel- 

 lowish white colour, with translucent dark brown intestine, and reddish ovaries.

Podoprionella, G. 0. Sars, n 



Body short and stout, with the metasome and urosome comparatively 

 poorly developed. Anterior pairs of coxal plates of moderate size, posterior 

 ones much smaller. Antennae (in female) short and snbequal in length; acces- 

 sory appendage of the superior ones small. Epistome scarcely projecting. 

 Anterior lip narrowly rounded. Mandibles with the cutting edge simple, trun- 

 cated, molar expansion obsolete, palp rather large, but sparingly setous, and 

 originating nearer the base than the tip of the mandible, terminal joint short, 

 lamellar. First pair of maxillse with the masticatory lobe divided into several 

 very coarse, unguiform teeth,- basal lobe not observed, palp normal. Second 

 pair of maxillae with the lobes very small, and each carrying only a few 

 simple spines at the tip. Maxillipeds with the basal lobes very narrow, masti- 

 catory lobes large, lamellar, both pairs nearly smooth, palps poorly developed, 

 not reaching to the tip of the masticatory lobes, terminal joint obsolete. An- 

 terior gnathodopa rather strong, terminating in a well-formed chela. Post- 

 erior gnathopoda very slender and of usual structure. Anterior pairs of 

 pereiopoda slender and nearly smooth ; the 3 posterior pairs with the basal joint 

 large and lamellar, its posterior edge being divided into coarse pectiniform serra- 

 tions. Uropoda rapidly diminishing in size; the 2 anterior pairs with the 

 rami narrow, and provided with a few serrations on the edges; last pair very 

 small, with both rami simple, mucroniform. Telson entire, squamiform. 



Bemarks. — This new genus agrees in some characteristics with the 

 genus Podoprion, recently established by M. Chevreux, but differs in several 

 other points very markedly, for instance, in the structure of the antennae and 

 maxillipeds, as also in that of the uropoda and telson. It contains as yet 

 but a single species, to be described below.
