 fine sand, temp. 9°57 C. One specimen, rather young. 



Aporrhais occidentalis, Beck. 



Rostellaria occidentalis, Beck, Mag. de Zool. 1836, pi. 72. 



30 / 6 , st. 70, lat. 42° 59' N„ long. 51° 15' W., 1100 

 m., temp. 3°7 C. One empty shell measuring 48 mm. 

 in height, the largest diameter being 34.5 m. 



A. occidentalis is distinguished from the European 

 species .4. pes-pelicani by the absence of spiral rigdes, 

 by having larger and more strongly developed 

 longitudinal ridges, and more rounded whorls. It is a 

 West Atlantic species, distributed along the east coast of 

 North America from New England to Labrador. In 

 addition it has been taken on the west coast of Green- 

 land. Its bathymetrical range is 4 to 1830 m.

T. berniciensis is an East Atlantic species, distributed 

 southwards to Cape Verde, the Canaries and the Azores. 



Northwards it is recorded by G. O. Sars 1 ) from as far 

 as Hasvik in Finmark. According to Dautzenberg and 

 H. Fischer 2 ) the Prince of Monaco has taken it to the 

 north of Spitzbergen, a statement which requires further 

 support as T. berniciensis has not hitherto been observed 

 in Spitzbergen waters. 3 ) Neither is it known from the 

 cold area of the Norwegian Sea excepting that the „Tri- 

 ton" took it in the cold area of the Faroe — Shetland 

 Channel 4 ) in 1882 (st. 8, 1331 m., -=- 1°1 C). This station 

 is, however, situated near to the warm area, and in such 

 places a few southern boreal species, the proper home 

 of which is the Atlantic and the banks surrounding the 

 basin of the Norwegian Sea, may be found in company 

 with high-arctic and boreo-arctic animals, as I have shown 

 in „Evertebratfaunaen paa havdypet utenfor Tampen". 5 ) 

 T. berniciensis is known from depths of 91 to 3120 m., 

 but in a living state it has not been observed deeper 

 than 2165 m. 



Neptunea (Sipho) gracilis, da Costa. 



Buccinum gracile, da Costa, Brit. Conch., 1775, p. 124, pi. 6, fig. 5. 



27 / 7 , St. 95, lat. 50° 22' N., long. 11° 44' W., 1797 

 m. Five specimens and two defective shells. The height 

 of the specimens varied between 14.5 and 54 mm., the 

 largest diameter between 7 and 225 mm. 



27 / 7 , st. 96, lat. 50° 57' N, long. 10° 46' W., 184 

 m. One specimen of medium size, defective, the lower 

 part broken off. 



Sipho gracilis has not previously been recorded from 

 greater depths than 1350 m. (the "Talisman" in 1883, st. 

 33). In obtaining it at st. 95 the "Michael Sars" extended 

 its bathymetrical range to between 37 and 1797 m. 



Neptunea (Sipho) pubescens, Verrill. 



Sipho pubescens, Verrill, Trans. Conn. Acad. vol. 5, 1882, p. 501, 



pi. 43, fig. 6, pi. 57, fig. 25. 



30 / 6 , st. 70, lat. 42° 59' N., long. 51° 15' W., 1100 

 m., temp. 3°7 C. Five specimens, of which two quite 

 young and an older one were living. The last named 

 measured, in height 56 mm., in largest diameter 23.5 

 mm. In the smallest specimen these dimensions were 10 

 and 5.5 mm. respectively, and in the largest of the two 

 empty shells 70 and 28 mm. 



I have had the opportunity of comparing the "Michael 

 Sars" specimens with three specimens of the typical
