CRUSTACEA MAIACOSTRACA. II. 



Remarks. As to this species I refer to Sars' description and good figures. It may only be 

 mentioned that the largest of the females measures 13.8 mm. and was taken by the "Ingolf ' ; the largest 

 male, 12 mm. long, is from Lat. 60 5' N. 



Occurrence. The "Ingolf has taken this species at a single station: 

 West Iceland: St. 87: Lai 65 02.3' N., Long. 23 56.2' W., nofm.; 7 spec. 



The "Thor" has secured it at 3 stations: 



South of Iceland: Lat. 63 46' N., Long. 22 56' W., 80 fm.; i spec. 



Lat. 63 15' N., Long. 22 23' W., 1141721111.; 5 spec. 

 South-West of the Fseroes: Lat. 6ii5' N., Long. 935'W., 400 500 fm.; numerous spec. 



Distribution. The species occurs along the whole coast of Norway, from Vadso to Christi- 

 ania Fjord, in depths from 30 to 150 fm. (G. O. Sars), and even 180 fm. (Norman). It has been taken 

 off Bohuslan (Lilljeborg), in the eastern part of Kattegat, 17 to 30 fm. and in Skager Rak, 70 to 226 fm. 

 (H. J. Hansen). Between the Shetland Islands and Norway it has been taken two times by Cand. mag. 

 Ad. Jensen ("Michael Sars") in 1902: Lat. 6io'N., Long. 2 35' E, 150 fm., temp. 7.9, i spec., and Lat 60 

 5' N., Long. 3 42' E., 190 fm., temp. 6.1, 21 spec.; the "Thor" secured it near the Orkney Islands: 

 Lat. 58 32' N., Long. 4 18' E., 150 fm. Tattersall has enumerated it from three places West of southern 

 Ireland and in such depths as 293, 320 and 375 fm., and according to Norman & Stebbing it was 

 taken off S. S. W. Ireland in 725 fm. According to Norman Apseudes Koehleri Bonn., established on 

 a specimen from the Bay of Biscay, is to be cancelled as a synonym to A.spinosus; but judging from 

 Bonnier's drawings that reference is still somewhat doubtful. 



2. Apseudes vicinus n. sp. 

 (PL I, figs, i a i c.) 



Immature Female. Allied to A.spinosus M. Sars, but differing in a number of features. - 

 The eye-lobes (fig. la) are more produced and more excavated in front than in A.spinosus, with the 

 result, that the transverse portion is very short and the outer process long, acute; the lateral process 

 behind the eye-lobe is more conspicuous than in the form mentioned, with the anterior margin 

 somewhat arcuate and the outer angle acute and a little produced. The lateral margin behind last- 

 named process is nearly straight excepting in front The upper surface of the carapace with the 

 transverse furrow very distinct, long. 



The antennulce in the main as in A. spinosus; the first joint with the proximal half of its 

 inner margin serrate; the outer flagellum 8-jointed, the inner 4-jointed and somewhat more than half 

 as long as the outer. Antennae with the flagellum 7-jointed; the squama reaches the end of the 

 penultimate joint of the flagellar peduncle. 



Chelipeds (fig. ib) nearly as in A.spinosus, but the lower margin of the carpus is somewhat 

 longer than that of the ischium while in A. spinosus the lower margin of the carpus is shorter than 

 that of the ischium and provided with two teeth not found in A. vicinus. 



Thoracic segments somewhat longer in proportion to breadth than in ~1. spiiiosus, and the
