tip and along the posterior edge with strong spines. Posterior gnathopoda 

 somewhat more elongated than the anterior, otherwise of the very same 

 strncture. The 2 anterior pairs of pereiopoda with the meral joint rather 

 expanded and triangular in form, carpal joint oblong fusiform in outline. 

 The 3 posterior pairs not very slender, but rather elongated, basal joint 

 narrow oblong in form, dactylus short and broad, scarcely exceeding in length 

 'A of the propodal joint. Last pair of uropoda with the basal part compa- 

 ratively narrow, rami rather broad and prominently foliaceous, with numerous, 

 ciliated setae on the inner edge, outer edge armed with small spinules. 

 Telson rather broad at the base, and gradually tapering distally, having on 

 each side, somewhat in front of the middle, 3 juxtaposed slender dorsal spinules, 

 and in addition 3 marginal ones, cleft extending nearly to the base, and somewhat 

 dilated at the bottom, terminal lobes slightly diverging, and obliquely trun- 

 cated at the tip, with the inner corner somewhat projecting, dentiform, each 

 lobe bearing 3 slender apical spinules. Body semipellncid, with a j^ellowish 

 orange tinge; ova in the marsupial pouch rose-coloured. Length of adult 

 female 12 mm., of male about the same. 



EemarJcs. — Tliis is the form upon which Kroyer founded his genus 

 Pardaliscn. Through the kindness of Dr. Hansen, I have had an opportunity 

 of examining the type specimens of Kroyer preserved in the Copenhagen 

 Museum, and find them to agree perfectly with the form here described. The 

 description given by Boeck of this species is somewhat misleading, in so 

 far as he erroneously indicates the length of the dactylus on the 3 posterior 

 jjairs of pereiopoda to be half that of the propodal joint. It is in reality very 

 much shorter, and the present species scarcely differs in that respect from his 

 other species, P. ahyssi. 



Occurrence. — Off the coast of Finmark, this form is not rarely met with, 

 in moderate depths ranging from 10 to 30 fathoms. I have for instance collected 

 it rather plentifully in the Varangerfjord at Vadso, and Mr. Schneider has 

 found it very abundantly in the Kvsenangenfjord, and also in the neighbourhood 

 of Tromso. It occurs also occasionally off the west coast of Norway, as for instance 

 at Christiansund, and extends, according to Bruzelius, as far south as Bergen.
