LAMEUJBRANCHIATA. 



The largest of these shells measures: height 10.5-""., length 6.5"""., the second largest is 

 8""". high. 



Specially characteristic (if this species seems to me the large number of radiating ribs (fig 

 under the lens they are seen to extend right to the ears of the shell; Jeffreys has counted about 

 50 ribs, and on my specimens I have counted 60 — 70 ribs. 



According to Jeffreys L.subovata has been taken in the Northern Atlantic elf the entrance 

 to the Denmark Strait, 1450 fm.; between the Hebrides and Faeroes, 542 I'm.; off the west oast oi 

 Ireland, 420—14431111.; off the Azores, 1000 fm. ; in the Western Mediterranean, 1450 fin. 1 ) 



Lima ingolfiana n. sp. 



PL II, figs. 9a— d. 

 The shell oval, somewhat oblique, moderately convex, silvery-white. The valves thin, with 

 ca. 30— 40 radiating ribs, the ridges of which are as a rule finely scaled or spined; the middlemost 

 ribs (or rib) are stronger than the others, thus giving rise to a median furrow (or two furrows); the 

 beaks prominent; the hinge-margin fairly short, slightly sloping, forming obtuse angles with the 

 lateral margins; cartilage-pit triangular; the internal surface glistening silvery-white. Height 5.2s 

 length 3.5 """. 



The "Ingolf" has taken this small, elegant species at Iceland at: 



St. 98. W. of Iceland 138 fm. 5.9 C. 1 valve. 



- 90. - - — 568 - 4.4 - 30 valves. 



- 78. vS. W. of 799 - 4.5 - 1 spec, and 20 valves. 



This species is well characterized by its somewhat oblique, more or less broadly oval contour, 

 the postero-dorsal margin forming a blunt angle not only with the hinge-margin but also with the 

 postero-median margin; as also by the rather well-marked sculpture of its finely scaled or spined 

 radiating ribs (fig. gd).

the Norwegian and the Dutch Exped. in the Norwegian and Barents Seas, as I believe, that they belong to my species 

 Lima hyperborea (see the latter).
