of the superior autennie, terminal edge narrowly rounded at the tip; post- 

 antennal corner nearly right-angled. First pair of coxal platens gradually 

 widening lielow, distal edge obtusely truncated, with ahout 7 strung plumose 

 setffi; each of the 2 succeeding pairs witli from o to 6 similar setae; 4tli pair 

 more than twice as broad as the preceding pair, and bearing on tlie distal edge 

 a series of about 10 setee; 5th pair reaching to about the middle of the posterior 

 expansion of the preceding pair, inferior corner bearing 4 curved setae. Last 

 pair of epimeral plates of metasome drawn out to a ver\- long and sharp 

 spiniform projection. Superior antennse nearly as long as the cephalon, 1st 

 joint of the peduncle very large, considerably longer than the other 2 com- 

 bined, and bearing at the inferior corner 3 large auditory bristles; flagellum 

 but slightly exceeding half tlie length of the pediincle, and composed of G 

 articulations; accessoi'y appendage somewhat shorter and 5-articulate. Inferior 

 antennae with the penultimate joint of tlie peduncle heart-shaped and beai'ing 

 po.steriorly 7 strong plumose setae and o cixrved spines, flagellum about the 

 length of the 2 outer joints of the pedirncle and 5-articulate. (Tuathopoda 

 nearly equal-sized, hands in both pairs oval, with the palmar edge slmrter 

 tlmn the liind margin. Penultimate pair of pereif)poda rather strong, scarcely 

 exceeding half the length of tlie body ; last pair with the basal joint rather 

 large, posterior expansion reacliing to the end of tlie meral joint, edge exhi- 

 biting a few, about 5, indistinct serrations, the 2 lower separated by a distinct 

 excavation. Last pair of uropoda very short, only slightly reaching beydiid 

 tlie ])receding ])air, inner ramus longer than tlie basal joint of the cmter, 

 niucroniforni and quite naked; outer ramus with 3 spines exteriorly, terminal 

 joint sijiniform, and exceeding half the length of the basal one. Lobes of 

 telson obtusely rounded at the ti^). Length of adult female 7 mm. 



Remarks. — Through the kindness of Dr. Hansen, 1 have luid an 

 opportunity of examining the type specimens of Kroyers Phoxus jihiuiofiiix from 

 (Ti'eeiiland, and find them exactly agreeing with the form here described, some 

 specimens of which are preserved in our University Museum, and were examined 

 by Boeck. There cannot therefore be any doirbt that this is the true Kroyeriau 

 species. The form described hy Stimpson as Phoxiis fusiformis is most probably 

 the same species. It is the type (if the genus. 



Ocairrence. — I have not myself met with this species oflF the coast 

 of Norway, and as the locality of the above mentioned specimens in our 

 University Museum, is not stated, it would seem to be questionable, wlietlier 

 this species at all can be referred to t lie fauna of Norway. Tlie binii geiit'i-ally 

 recorded bv other authors as If. j)liiniosa is evidently not that species, liiit the 

 following one, and Boeck himself must |iriili;ibly confounded Ixith, though he
