a tUstinct angle, palm nearly straig-lit and armed witli rucurvud tuctli, those at 

 the extremity much stronger and claw-like; dactylus very stroiig, curved at 

 the tip. Posterior gnathopoda very slender, propodal joint oval and densely 

 hairy, dactylus yery small and rudimentary. Meral jiunt of tlie 2 anterior 

 pairs of pereiopoda, especially that of the 2nd jjair, lanunarly dilated. The 

 3 posterior paii's of pereiopoda comparatively short, successively increasing 

 in length, hasal joint laminar, and forming in the anterior ones an angular 

 projection posteriorly. Uropoda only sligtly decreasing in size posteriorly, 

 rami subeqi^al. Telson rounded, almost as broad as it is long, tip obtusely 

 truncated. Colour') whitish, with a more or less distinct light reddish tinge 

 on the sides of the body. Length of the largest specimen examined 28 mm. 

 , Ilcniarls. — This is the only, as yet, known species of the genus. 

 All the si)ecimens, which have hitherto been examined, were females, some of 

 which liad their incubatory pouch tilled with eggs or young. In the latter, 

 as stated, above, the anterior gnathopoda have not yet assumed their peculiar 

 torsion and of course exhibit an appearance rather different from that of the 

 adult animal (see tig. p' jr.) 



Occurrence. — The present remarkable form was tirst detected bj^ the 

 late Prof, llasch on the Storeggen-bank, outside of the west coast of Norway, 

 from a de])th of about 100 fathoms. The specimens were obtained by sub- 

 merging in the dredge the skinned body of a newly shot bii'd to which they 

 were found clinging. It has subsequently been taken by Mr. Storm, curator of 

 the Drontheim Museum, from the skin of the common black dog-Ush (Sjnnax niger), 

 fished in the neighboiu'hood of the town. Finally Dr. Bovallius procured a 

 few specimens at Tjoto in Nordland and in the Hardangerfjord. No doubt 

 the species leads, as a rule, a parasitic life, and this may easily explain the 

 peculiar formation of the anterior gnathopoda and oral parts. Out of Norway 

 this form has not vet been recorded.
