CRUSTACEA MALACOSTRACA. 51 



my material of A", lar, amongst which are Kroyer's type-specimens, lias shown me that the carina 

 mentioned ends in a right-angled 01 pointed tooth sharp to the touch. I find that my X. lar in the 

 form ol the posterior edge of the carina, in the slender form of the r 1 thoracic hand, Imt not in the 

 form of the squama, agrees better with .V. dentata Rathb. than with N. lar sens. Rathbun. And I be- 

 lieve that A", lar Kr. is identical not only with N. dentata Rathb. but likewise with A', lar sens. 

 Rathb., and that future investigations will come to the same conclusion as mine, namely, that Miss 

 Rathbun's two species cannot be separated from one another. According to the founder, the A', den- 

 tata has almost precisely the same geographical distribution as her A', lar, but is found in from 6 to 

 96 fin.; she also ascribes specimens from Granville Bay (between 76 and 79 N. L.| on the west coast 

 of Greenland to A", dentata. I have mentioned the whole question in such detail, because the literature 

 thus gives a Nectocrangon dentata as occurring at West Greenland, which belongs to the area dealt 

 with in this paper.

Occurrence. The "Ingolf" has taken this beautiful form at 3 stations. 



Davis Straits: St. 28: 65 14' N. L., 55 42' W. L., 420 fm., temp. 3-5°; 1 spec. 

 - 27:64° 54' - 55 10' - 393 - 3-8°; 4 - 



South-West of Iceland: St. 83: 62 25' N. L., 28° 30' W. L., 1912 fm., temp. 3-5°; 1 spec. 



Distribution. Previously the species was only known from Guadeloupe, 734 fm., and off the 

 east coast of America between 35° 45' N. L. and 41 53' N. L. in depths from 353—888 fm. The distri- 

 bution of this Atlantic form far up in the Davis Straits is interesting. 



Remarks. The largest specimen, a fine female with eggs, is 114mm. and was taken at St. 27.

Occurrence. Has been taken by the "Ingolf" at 3 stations: 

 Davis Straits: St. 31: 66° 35' N. L., 55 54' W. D, 88 fm., temp. r6°; 14 spec. 

 West of North Iceland: St. 15: 66° 18' N. L., 25°59'W. L., 330 fm., temp. -^ 075 ; 3 spec. 

 North of the Faeroes: St 143: 62° 58' — 7°09' — 388 — — -^0-4°; 1 — 

 In Malac. Groenl. this species is mentioned from two localities in the Davis Straits: later, I 

 have obtained it from three others (apart from the "Ingolf); a resume of my knowledge of its occur- 

 rence in the waters mentioned would read as follows: it is taken between 66',° and 63V2 N. L. in 

 depths from 67 to 140 fm. I have further seen specimens from the following localities; 

 Northern Iceland: Skagestrandsbugten, 119 fm., temp. 2-9', mud, Wandel; 1 spec. 



_ _ 66°i7'N. L., i8°i3'W. L., 50 fm., mud, "Thor" 1903; 1 spec. 



West of Iceland: 66° 20' — 25 12' — 96 fm., temp. 6-5°; mud, "Thor" 1903; 4 spec.
