CRUSTACEA MALACOSTRACA. II. 17 



the distal part of its lower margin, while all adult females of .S'. serratus have three such spines (in 

 a single specimen only two spines on one leg and three on the other); furthermore the basal joint of 

 the antennulse is a little broader and shorter in S. aiioiualiis than in S. serratus. 

 Occurre|nce. The "Ingolf" has taken this species at eight stations.

 Furthermore the species has been taken at East Greenland by two Danish expeditions. 



Cape Dalton: Lat. 69° 24.6' N., ab. Long. 23° 30' W., 9— 11 fm., II'' Amdrup Exp.; large number 



of specimens.

Distribution. S. aiwntalns has been captured by Cand. mag. Ad. Jensen ("Michael Sars") at 

 two places North-East and East of the Shetlands Islands: Lat. 61° 40' N., Long. 3°ii'E., 220 fm.; i 

 spec, and Lat. 6o''57'N., Long. 3°42' E., 190 fm., temp. 6.1°; i spec. The "Thor" has captured it in the 

 Skager Rak in depths from 280 to 350 fm. Sars has taken it "along the whole Norwegian coast from 

 the Christiania Fjord to Vadso", in depths "from 100 to 400 fathoms". Finally it is known from the 

 Kara Sea, 50 fm. (Hansen) and from the places South of Novaia Zemlia, between Lat. 70° 20' and 

 70° 40' N., Long. 54° 08' and 56° 35' East, 61 and 90 meters (Stappers). 



According to all these statements S. aiwmalus has been taken a single time in 50 fathoms in 

 the very cold Kara Sea, three times in still lesser depths South of Novaia Zemlia and at numerous 

 places in depths between 100 and 582 fathoms both in the cold area and especially at localities with 

 the temperature somewhat or even considerably above the zero.

The differences between this species and -S; anomalus have been pointed out above. 

 Occurrence. The "Ingoir has captured S. serratus at five stations, all in the cold deep- 

 sea area.
