JAMES A. GRIEG 



[REP. OF THE "MICHAEL SARS" NORTH 



from the northern Thesbia nana, Loven, that it cannot 

 be referred to the same genus as that species. 



B. nudator has hitherto been recorded only from 

 the great depths to the north of the Azores (the "Talis- 

 man" 1883, st. 134, 4010—4060 m.). 



Surcula tenerrima, P. Fischer, var. 

 Fig. 11—12. 



Surcula tenerrima, P. Fischer M. S., Locard. Exp. Sci. "Travailleur"

 1897, p. 216, pi. 9, fig. 30—33. 



1 a, st. 10, lat. 45° 26' N., long. 9° 20' W., 4700 

 m., yellow mud, temp. 2° 56 C. One empty, somewhat 

 eroded shell, 58 mm. high, 20.5 mm. broad, height of 

 mouth with channel 37.5 mm., breadth of mouth 11 mm. 



I have referred this shell to Locard's Surcula 

 tenerrima as it resembles that species both as to form 

 and sculpture though it is larger, Locard giving the 

 height of his species as 35 mm. and breadth 12 mm. 

 Furthermore the last whorl is rather more swollen in 

 our specimen, the most significant difference being however 

 that it has more numerous and finer spiral ridges. To 

 judge from Locard's drawings some of the spiral ridges 

 are larger and more prominent than the rest in the 

 typical 5. tenerrima. On the basis of these differences 

 I have entered the "Michael Sars" specimen as a variety 

 of S. tenerrima, not deeming them significant enough to 

 found a new species upon them. 



Previously S. tenerrima was known only from the 

 Sargasso Sea, 3125 m., and from the depths to the north 

 of the Azores in 4010 to 4060 m., where the "Talisman" 

 dredged it together with the preceding species. 



Pleurotoma projecticiutn, Locard. 



Pleurotoma projecticium, Locard, Exp. Sci. "Travailleur" et 



"Talisman", Mollusques Testaces, tome 

 1, 1897, p. 197, pi. 9, fig. 1—6. 

 23 / 3 , st. 41, lat. 28° 8' N., long. 13° 35' W., 1365 

 m., yellow mud. One specimen 14.5 mm. high, 5.5 

 mm. broad. 



P. projecticium was taken by the „ Travailleur" and 

 the "Talisman" off the west coast of Morocco in 1590 to 

 1910 m., and in the Sargasso sea in 3530 m.

 20 /s, St. 37, lat. 26° 6' N., long. 14° 33' W., 39 m., 

 shingle. One rather large specimen with very damaged 

 shell. 



Marginella impudica, P. Fischer. 



Marginella impudica, P. Fischer, Journ. Conch, vol. 31, 1883, p. 392. 

 5 /s, st. 21, lat. 35° 31' N., long. 6° 35' W., 535 m., 

 yellow sand, temp. 11° 52 C. 



One specimen 7.5 mm. high and fragment of another 

 about twice that size. 



23 / 5 , st. 41, lat. 28° 8' N., long. 13° 35' W., 1365 



m., yellow mud. Four specimens two of them quite 



young. Dimensions of the five specimens in millimetres: 



No. 1 No. 2 No. 3 No. 4 No. 5. 



from st. 21 



Height 28.2 17 7.5 7.5 6.5 



Breadth (max. 



diameter) 13 9 4.7 4.5 3.7 



Height of mouth. 19.5 12.7 6.5 7.0 5.5 



do. do. 

 in % of height 69.1 74.7 86.7 93.3 84.6 



The two largest specimens must be referred to the 

 variety minor, Locard, from which they differ in size, 

 as the variety minor, according to Locard, attains a 

 height of only 25 mm. 1 ). As will be seen from the table 

 above the three small specimens have a comparatively 

 lower spire than the large ones. In form they rather 

 resemble Marginella parvula, Locard 2 ) than M. impudica, 

 but the reason why I have referred them to Fischer's 

 species is that all five specimens exhibit the same sculpture 

 and the same shining rosy colour, and that the comparative 

 height of the spire seems to increase with increase of 

 size, being greatest in the largest specimen, a litte smal- 

 ler in specimen no. 2 and smallest in the three small 

 ones, nos 3 — 5, while the broken specimen from st. 21 

 is intermediate between these and no. 2. It must have 

 been about 14 mm. high, with the height of mouth about 

 78 % of the total height. From the dimensions of the 

 three small specimens it is however seen that individual 

 differences occur regarding the comparative height of the 

 mouth, this ratio being greater in the specimen 6.5 mm. 

 high than in the two 7.5 mm. high and of these two it 

 is greater in the specimen from stat. 21. 



Marginella Impudica has been taken by the "Talis- 

 man" off the west coast of Africa and near the Canary 

 Islands where also the Prince of Monaco obtained it. Its 

 bathymetrical range is from 102 to 1355 m.
