of .-I. n,t,rmfdia shows considerable variation in the relative length of first joint of the antcnnal 

 him, ami even some variation in the relative length of the distance between the tip of abdomen and 

 the end of the uropods. At all events my remarks and figures may, I hope, render the form easily 

 recognisable to some future Carcinologist who has a richer material at his disposal 

 Occurrence. Taken by the "IngolF at a single station. 



Davis Strait: StaL 35: Lat 6?y>' N, Long. $4*2$' W., 583 fath., temp. 3-3; i spec 

 Distribution. Only three specimens are known, viz. two from Hardanger Fjord, West Nor- 

 way, 60100 fath. (G. O. Sars), while the third specimen has been taken midway between Norway and 

 Shetland in 58 or, more probably, 97 fath. (Zirwas).

The largest specimen, an ovigerous female, is 14-5 mm. The relative length of the joints in 

 its antennal flagella agrees nearly with Sars' figure, the first joint being at least half as long again 

 as the two other joints combined. 



But it may be noted that our Museum possesses 4 specimens of co-types of A. a/finis presented 

 l>v Sars; the largest of these specimens, a female with marsupium, measures 16-5111111., is thus 3-5 mm. 

 longer than the length recorded by Sars, and in this specimen the two distal joints of the antennal 

 flagella combined are not shorter than first joint, thus showing that the character afforded by the rela- 

 tive length of the first joint is somewhat poor. 



Occurrence. Not taken by the "Ingolf, but by the "Thor" at a single place. 



South of Iceland: Lat 63i5' N., Long. aa23' W., 114173 fath.; 6 spec. 



Distribution. At Norway in Trondhjem Fjord, 100300 fath., and off Lofoten, 300300 

 fath. (G. O. Sars). A specimen probably belonging to this species was taken in Skager Rak not far 

 from the Skaw, 70 fath. (H. J. Hansen). It has been recorded from Lat 5954*N., Long. 6*n'E n 63 

 fath. (Zirwas); from Fair Island between Orkney and Shetland (T.Scott); from the Firth of Forth; at 

 Durham and off South-West Ireland, 100200 fath. (Norman), finally from four places west of Ireland, 

 in from 130 to 199 fath. (Tattersall). 



142. Astacilla pusilla G. O. Sars.

Sars has noted that the adult female scarcely exceeds 8 mm. in length; my two females with 

 marsupium are respectively 108 mm. and about 12 mm. long, but belong unquestionably to this species. 



Occurrence. Not taken by the "Ingolf, but by the "Thor" at a single place. 



South-West of the Faeroes: Lat 6i c is' N, Long.935' W, 463515 falh.; 3 spec 



Distribution. Hitherto only known from three places at West Norway: off Sognefjord, 

 209 fath. (G. O. Sars, 1886); Storeggen bank, and off Lofoten, 80100 fath. (G. O. Sars, 1897).
