M. Yayssiriv (l!H. r ), p. 143) thinks that the din'erent types of Lininciini called 

 i'<'f/-<>ccrxuH, trochiformis, l><il<<t and austTdlis all lielonn' to one species, and that the 

 differences of the shell are due in realitv only to tin- differences of a^'e in the 

 individuals studied. As far as the " Terra Nova " specimens are concerned there are 

 too few individuals, and these are not in sufficiently good condition to make a 

 comparative investigation of such minute forms possible. The shells are completely 

 destroyed in all, lint as regards the external appearance of the animal the specimens 

 noted aliove possess characters which agree so closely with the description and figures 

 of Hoimevie (1913) of L. bali-n, and are so very different in appearance to the specimens 

 referred in this report to L. rdrnret'fut (Flem.), that I think it is 1 tetter to keep the two 

 forms apart here, particularly as they occurred in widely different localities. It may 

 lie remarked, however, in support of .M. Yavssiere's view, that the specimens referred 

 to L. ri'trni-i/'sii are all smaller than those placed under /.. balea. In specimens 

 of the latter, from station 250, the spire varies considerably in the proportion it 

 bears to the last whorl, but the whorls are much more graceful in general contour 

 and blend with one another more imperceptibly than in the abruptly-spired, squat 

 //. retfoct'i'xd. 



The specimens taken off the west of Ireland and referred (.Massy, I '.)<>!)) 

 to L. retroversa (Flem.) were mainly, if not entirely, referable to the present 

 species.
