Occurrence. The "Ingolf" has been so fortunate as to take this beautiful species at one station. 



West of Iceland (halfway between Iceland and Greenland): St. 11: 64° 34' N. L., 3i°i2'W. L., 

 1300 fm., temp. i-6°, 2 specimens. 



Distribution. On the American side of the Atlantic this species has been taken at Bequia, 

 Antilles (1591 fm.) and from there northwards to 40° 17' X. L. It was also taken by the "Talisman" 

 off northern Africa at about 30° N. L.; these specimens were described by A. Milne-Edwards as G. Talis- 

 mani, under which name a .specimen from Banda (ca. 130° E. L.) was included by Henderson in the 

 "Challenger" Anomura, p. 167, PI. XX, fig. i; later, Milne-Edwards & Bouvier included G. Talisiiiaiii as 

 a synonym and also considered the Banda specimen as belonging to G. rostrata. Henderson (1. c. p. 167, 

 PI. XIX, fig. 6) also describes a G. bcllis and considers it different from G. rostrata, but it is taken as 

 a variety by the Erench authors. Faxon (^Mem. Mus. Comp. Zool. Vol. XVIII, p. 78, PI. P., figs, i, i a) 

 had however in 1895 already both disputed the correctness of considering G. bcllis as a species and 

 liad referred seven specimens taken at three stations west of Columbia or north of the Galapagos Is- 

 lands to G. rostrata. He adds, it is true, that his specimens "differ constantly from the typical West 

 Indian form in the following particulars", Ijut tliese seem to be small. In 1901, Alcock (Descrip. Catal. 

 p. 274) gives G. rostrata as having been taken in the Arabian Sea and Bengal Bay in depths from 

 1022 to 1520 fm. To sum up, during the last ten years authors have come more and more to the 

 conclusion, that the specimens taken in the different seas belong to G. rostrata and that this shows 

 some variation in the length of the .sj^ines and in the sculpture. I think that A. Milne-Edwards &. 

 Bouvier are quite right when they say (1900), that ''G. rostrata est une espece cosmopolite repandue 

 vraisemblablement dans les profondeurs de toutes les mers chaudes ou temperees". The "Ingolf" has 

 now also shown that the species occurs at ca. 64' / N. L. between Iceland and Greenland; the surface- 

 water here belongs to purely arctic regions, but in deep water at 1300 fm., where the species was 

 taken, the temperature and other conditions of the sea are certainly nearly identical with those found 

 in similar depths between the tropics. G. rostrata has only been taken in depths between 1022 fm. 

 (Arabian Sea) and 1591 fm. (Antilles). 



Remarks. Both my specimens are males; the larger is 58 ram. long to the tip of the rostrum. 

 \Mien they had just come from the water I noticed that they were reddish yellow in colour with pale 

 red eyes.
