Mediterranean, and according to Jeffreys in Japan 1 ). 

 Dall mentions it from Norway 2 ), though this seems to 

 be a misstatement for the preceding species. G. O. Sars, 

 Friele, Sparre Schneider, Nordgaard, Jeffreys and 

 Norman mention only Limopsis minuta from the Nor- 

 wegian coast, and the specimens of Limopsis I have 

 had the opportunity of examining from the west and 

 north coasts of Norway belong exclusivily to that species. 

 The bathymetrical range of Limopsis aurita is between 

 38 and 3175 m.

Area profundicola, Verrill & Smith. 



Area profundicola, Verrill, Trans. Conn. Acad. vol. 6, 1884, p. 

 439, tab. 44, fig. 23. 



8 / 6 , st. 53, lat. 34° 59' N., long. 33° 1' W., 2615— 

 2865 m., yellow, hard clayey mud. One specimen 

 measuring: alt. 4 mm., lat. 8 mm., crass. 2 mm. The 

 type specimen measured 7, 12 and 5 mm. respectively. 

 Our specimen conforms with the type in form and struc- 

 ture, but has a whitish yellow epidermis, the coating 

 being dark-brown in the type specimen. 



This species is closely related to Area peciunculoid.es, 

 and is, perhaps, only a deep-sea variety of it. Having 

 however in my possession only a single specimen, which 

 differs from the Area pechincuioid.es occurring on the 

 Norwegian coast, I have treated it as a distinct species, 

 as Verrill, Dall 3 ) and Kobelt 4 ) have done. 



Area profundicola has not been reported before from 

 the Eastern Atlantic. It is known only from the great 

 depths off New Jersey ("Albatross", st. 2226, lat. 37° 0' 

 N., long. 71° 54' W., 3698 m.).

9 /4, St. 1, lat. 49° 27' N., long. 8° 36' W., 146 m., 

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

 3.5 mm., lat. 4.2 mm. 



Syndesmya longicallus, Scacchi. 



Tellina longicallus, Scacchi, Ann. Civ. Regn. d. due Sic, vol. 4,

"A, st. 10, lat. 45° 16' N., long. 9° 20' W., 4700 

 m., yellow mud, temp. 2°56 C. One well-preserved 

 right valve, alt. 11 mm., lat., 17 mm. 



In 1869 the "Procupine" took this species off the 

 Channel in a depth of 4456 metres (st. 37) 1 ), this being 

 the greatest depth hitherto recorded for the species, but 

 now superseded by the present record establishing a 

 bathymetrical limit of 4700 m. 



Mytilimeria flexuosa, Verrill & Smith. 

 (Figs. 1—4.) 



Mytilimeria flexuosa, Verrill, Amer. Journ. Sci. ser. 3, vol. 22, 

 1881, p. 302. 



6 — 7s, St. 101, lat. 57° 41' N, long. 11° 48' W., 

 1853 m., hard clay. Three specimens and a right valve 

 with an ascidian. 



The specimens measure (in milimetres). 



No. 1 No. 2 No. 3 



Alt 50 49 46.5 



Lat 41.5 43.5 48 



Crass 48.5 45 46 



Breadth % of height 83 88.8 103.2 



Thickness % of height 97 91.8 98.9 



These figures reveal the great variations the form of 

 the shell is subject to, and this is still better demonstrated 

 if the above figures are compared with those given by 

 Verrill and Dall. In Verrills type specimen the breadth 

 of the shell is 88 % of the height, the thickness 104 %>. 

 In Dall's specimen both the breadth and the thickness 

 exceed the height viz 115.4 %. 



Dall describes and figures minutely the anatomy of 

 this species 2 ) In the "Preliminary Cataloque of the shell- 

 bearing marine Mollusks and Brachiopods of the South- 

 eastern Coast of the United States" 3 ) he gives furthermore 

 a drawing of the outer surface of a left valve. Verrill 

 describes both the animal 4 ) and the shell, and gives a 

 drawing 5 ) of the latter. Locard, finally, gives some draw- 

 ings of a defective shell. 6 ) As none of the drawings 

 extant of the shell of this mollusk is altogether satis- 

 factory, I take the opportunity of giving some fresh 

 drawings of it. 



Mytilimeria flexuosa was first found off the coast of 

 New England, in 571 m., and was subsequently taken
