tlialmiis. Scolofililliahiiiis stands near to Ffaiisci/oi//ysis and seems essentially only to differ from this in 

 that the stalk of the antennules is considerably elongated and the carapace prodnced into a relatively 

 large rostrnm.

Occnrrence. The "Ingolf has taken this .species at 13 stations. 

 South of Jan Mayen: vSt. 113: 69°3i'N. L., 7° 06' W. L., 1309 fm., temp. -=- i-o°; 17 spec.

 One .specimen was taken by the "Thor" east of Iceland: 66° 19' N. L., 10° 45' W. L., 760 fm. 



Ohlin notes it from a place between East Cxreenland and Jan Mayen: 72° 42' N. L., 14° 49' W. L., 1053 fm. — 

 It is easily seen that all the localities lie in the cold area north of the Fceroes to the east and north- 

 east of Iceland, also as far north as Jan Mayen and between this island and East Greenland; the 

 depth \-aried between ca. 760 to 1309 fm., the bottom-temijerature between -=- o-8° and -f- i-i°. 



Distribution. Ct. O. vSars founded the species on .some specimens taken in the waters X. W. 

 of Finmark: 71° 59' N. L., 11° 14' E. E., iiiofm., temp. -^ 1-3°. Ohlin gives it from two places considerably 

 further north, namely, 77° 52' N. L., 3° 5' W. L., 1455 fm., temp. -^ 1-4° and 78° 19' N. E., 8° 41' E. L., 1.130 fm., 

 temp. -^ 1-4°. In his work on the Schizopods of the "Challenger", Sars refers a number of specimens 

 taken at 3 stations in the southern (")cean to this species; the stations lie between 46" 16' and 53" 55' 

 S. E., the depth varied from 1600 to 1950 fm. and the bottom-temperature was over 0°. Being no be- 

 liever in bipolarity I have always supposed that the last-named specimens belong to a different species; 

 besides B. scyphops is not known from any place between the Northern Ocean and the Antarctic Sea, 

 and the bottom-temperature is below zero at all arctic station.s, above zero in the antarctic localities. 

 In June 1907 I went to Eondon taking with me some specimens of m\- I), scyphops for coinparisoii 

 with the antarctic sijecimens, and the result arrived at will be given presently. 



Remarks. The largest of mv numerous specimen.s, a female with marsupium, is 60 nnn. from 

 the tip of the rostrum to the end of the telson. Sars gives 70 nmi., but does not state how the 

 measurement was taken; the largest "Challenger" specimens from the Antarctic Sea is gi\en by him
