CRUSTACEA MALACOSTRACA. III. 39 



It may be added that the legs are, as usual, distinctly varying as to length and thickness, 

 being strongly or moderately strongly built, and the posterior pairs proportionately moderately short 

 or somewhat long. 



Remarks. This characteristic species was certainly mistaken for, or confounded with, M. 

 Kroyeri or M. Boeckii by several authors until 1910. 



Occurrence. Not taken by the "Ingolf". 



At West Greenland it has been gathered at two places, viz. by Th. Holm at Upernivik (Lat. 

 72°47' N.), 10 fath., and at Godthaab (Lat. 64°n' N.), c. 50 fath., Holboll; as already stated, I found 9 

 specimens of M. Fabricii together with 6 specimens of M. groenlandica, all named M. Fabric//, in all 

 probability determined by Kroyer, and originating from the last-named locality. - - It is not known 

 from East Greenland. 



M. Fabric// is common at Iceland, where it has been taken by several zoologists at the following 

 places. Off the west coast at Stykkisholmr in Brede Fjord, 30 fath.; off the north coast at Grimsey, 

 15 fath.; off the east coast at Skalanes, 7—8 fath., in Faskruds Fjord, 20 — 50 fath., at Djupivogr, 8 fath., 

 and 9 miles off the coast, 38 fath., finally south of Iceland: Lat. 64°i7' N., Long. i4°44' W., 44 fath. — 

 Hitherto not known from the Faeroes. 



Distribution. At Denmark this species has been gathered in Langelandsbeltet, 15 fath. 

 (H. J. Hansen). The Copenhagen Museum possesses it from the North Sea, Lat. 57°i6' N., Long. 5°3o' 

 E, 30 fath. (taken by Capt. Orsted) and 1 old specimen from the west coast of Norway. It has been 

 recorded from the south coast of Novaya Zemlya, Lat. 70°2o' N., Long. 56°35' E., 48 fath. (Stappers), and 

 the specimens from Northbrook Island, Franz-Joseph Land, referred by T. Scott to M. Kroyeri probably 

 belong to M. Fabricii. Whether M. Brandti Zirwas (1910), recorded from sixteen places in the North 

 Sea, belongs to M. Fabricii Kr. cannot be decided with certainty, but it is highly probable. More cannot 

 be said on the distribution, as authors certainly have confounded it with other species.

The description and figures published by Sars together with my notes and figures quoted may 

 be quite sufficient for recognizing this small and thin-legged species. It may, however, be added that 

 an examination of my large materiel has given the result, that in some specimens the abdomen — its 

 free basal segment not counted — is about as narrow as figured by Sars and is furnished with a pair of 

 small and slender lateral spines, while in the majority the abdomen has no lateral spines and is either 

 as broad as in fig. 2 c in my paper quoted or shows every shape intermediate between this figure 

 and the figures of Sars. Consequently the abdominal shield varies from being slightly longer than 

 broad to slightly more than half as long again as broad, but it is always ovate, broadest considerably 

 before the middle. 



Finally an important specific character may be added. The median lamella of the male operculum
