CRUSTACEA MAUACOSTRACA. IV. 



as might be expected ; besides the carpus of third maxillipeds has distully on the outer side 3 teeth, and the 

 end of second joint of first leg 2 teeth not found on Caiman's figures. 



Length of ovigerous females 5.5 — 5.7 mm. 



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



South-West of Iceland: Stat. 81: Lat. 6i°44' N., Long. 2/°oo' W., 485 fath., temp. 6.1°; 1 immature 



male. 

 Besides the "Thor" captured this form at 3 places. 



South of Iceland: Lat. 63°I5' N., Long. 22°23' W., 114 — 172 fath.; 1 immature male. 



South-West of the Fseroes: Lat. 6i°i5' N., Long. 9°35' W., 463 — 515 fath. ; 17 specimens, most of 



them adult females. 



Lat. 6i°7'N., Long. 9°3o' W., 443 fath.; 5 adult females. 



Distribution. Hitherto known only from a single locality west of Ireland, viz. yy miles W.N. W. 



of Achill Head. co. Mayo, 382 fathoms. 



PrOCampylaspiS Bonnier. 



This interesting genus is easily separated from all other genera by the curious shape and armature 

 of the terminal joint of second pair of maxillipeds. It may be remarked that first pair of legs are long, consider- 

 ably longer than second pair, while in Campylaspis first pair are at most slightly longer and generally shorter 

 than second pair. Only 4 species are recorded by Stebbing (1913), 2 among them from the southern hemi- 

 sphere. In the "Ingolf" area 2 new species have been discovered, and it may be possible that a third species, 

 P. artnata Bonnier, also can be found 1 . 



29. Procampylaspis bituberculata 11 sp. 



(PI. II, figs. 7 a— 7 m.) 



Subadult Female. Carapace, seen from above (fig. 7 b), almost half as long again as broad, 

 somewhat oblong-ovate and rather narrowed forwards; considerably behind the middle a pair of propor- 

 tionately large, broad and somewhat low, conical protuberances, each with a small spine on the top. Seen 

 from the left side (fig. 7 a), the dorsal line shows the shape of left protuberance; pseudorostrum is turned 

 sharply and considerably upwards, and its anterior margin is straight, yet directed from above a little back- 

 wards, without any notch, and the corner between this line and the lower margin is a very obtuse angle. 

 The ocular lobe is narrow with the sides parallel, not half as long as pseudorostrum and without eyes. The 

 free thoracic segments in the main as in P.armata; first segment dorsally at the middle produced as a small, 

 bifid lamina with its two teeth curved distinctly forwards, second segment with similar, but nearly vertical 

 teeth ; fourth and fifth segments each with a pair of teeth somewhat from the median line. First abdominal 

 segment with a pair of dorsal granules; otherwise granulation on the abdominal segments is indistinct or 

 wanting. 



1 Of P. armata Bonn., first gathered in the Bay of Biscay, later in the Mediterranean and west of Ireland. 2 females 

 and 1 male have been taken by the "Thor" in 1905 at I.at. 0U14 X., Long. i°i9 E., 85 fath. thus north-east of Shetland.
