, Q CRUSTACEA MALACOSTRACA. III. 



(fig. 6a) has several ventral spines on its proximal third; it is conspicuously broader than in any of 

 the other species, only twice as long as broad, considerably constricted somewhat from the end, and 

 then widening strongly to the end; each distal angle is produced into a somewhat long, spiniform, 

 acute process directed mainly outwards; the long hind margin of each pleopod is a little sinuate and, 

 in the main, transverve. Length of the largest females with marsupium (from West Greenland) 2-5 mm. 



Occurrence. Not taken by the "Ingolf". 



It must be common at West Greenland, as it has been taken by several collectors off that coast 

 at six places, from Lat. 72°43' N. to about Lat 6o°43' N. The places are: Upernivik, 10 fath.; Egedes- 

 minde; Lat. 66°3o' N., Long. 54°5o' W., 40 fath.; Lat. 64°52' N., Long. 53°io' W., 28 fath.; Godthaab, 4—10 

 and 25 fath.; finally not far from Julianehaab, 22 fath. — In East Greenland it has been taken by 

 Mag. Kruuse at Angmagsalik (Lat. 65°3o' N.) and Tasiusak (Lat. 65°37' N.); by the Ilnd Amdrup Exp. at 

 Lat. 66°i5', low water. 



Near Iceland it has been taken by several zoologists at the following places. Off the west 

 coast at Reykjavik (G. O. Sars) and in Talkna Fjord, 14 fath. Off the east coast in Yid Fjord, 8-12 

 fath.; in Bakka Fjord, 2—4 fath.; in Faskruds Fjord, 20—50 fath.; in Breiddals Vig, 6 fath.; at Djupi- 

 vogr, 8 fath.; 9 miles of the coast, 38 fath.; finally south of Iceland at Lat. 64°i7' N., Long. i4°44' W., 

 44 fath. — At the Faeroes it has been secured by Dr. Th. Mortensen twice: north-west of Kalso, 60 

 fath., and off Bor6, 20—30 fath. 



Distribution. Taken a few times in Kattegat and Skager Rak, going down to 70 fath. 

 (H. J. Hansen); off the west coast of Norway and "along the whole Finmark coast, in moderate depths" 

 (G. O. Sars). Recorded from Cape Flora, Franz-Joseph Land, 30 fath. (T Scott), from the south coast 

 of Novaya Zemlya, 48 fath. (Stappers), and from Advent Bay, Spitzbergen (G. O. Sars). Besides from 

 the North Sea, 34 fath. (Zirwas), from a few places at the west and south coasts of England (Norman), 

 and the west coast of Ireland, 6—7 fath. (Tattersall). — According to Harger's description of the anten- 

 nulse the animals from the east coast of New England referred by him to M. Fabricii cannot be this 

 species, and as Richardson in the Monograph copied the text and figures of M. Fabricii G. O. Sars, 

 but anions: the localities has most of those noted bv Harger, the statements are of no value.

 (PI. Ill, figs. 7 a- 7 h.) 

 Description. As to general shape of the body and length of the legs somewhat similar to 

 M. limicola G. O. S. The upper surface of the body has always a number of hairs, and in some spec- 

 imens the clothing is somewhat dense. — The front margin of the head armed with some very robust, 

 horizontal spines, generally 4 (fig. 7 c), but sometimes 2, 3 (fig. 7e) or 5 (fig. 7 a). Eyes completely wanting, 

 but the eye-stalks are very conspicuous and much varying as to length (figs. 7 a and 7 e), being from 

 moderately short to extremely long, always conical, acute and curved a little or somewhat forwards. 

 - Antennulse (figs. 7 a and 7 f) nearly as in M. limicola; the basal joint somewhat large, but longer 

 than broad; second joint somewhat long and the third short; flagellum 5-joiuted, with 3 of the joints long. 

 The thoracic segments vary much in armature. Each segment has most frequently at the
