l.-,-J "TEKKA NOVA'- EXPEDITION. 



L. cosiala as regards the basal lialf. They do not refer to it in their text, and 

 in tire description of the plate it is merely referred to as an intermediate variety 

 of L. melo, d'Orb. Identical specimens occur in the Antarctic area, and in these 

 circumstances Brady's figure can no longer be regarded as a freak, but nuist be 

 given a definite name. The best specimens were from Stations 48 and 50.

Williamson's variety of L. .squamosa, vai-. aiiciinlafa — and his figure, agree 

 Avitli L. mdo, d'Orbigny. His authorship therefore lapses in favour of l^euss, whose 

 fig. 75 of L. catenulata, Williamson, represents a different test, which is the one 

 now before us. Reuss's figure represents a shell with a limited number of costae 

 (12-14 in number) between which are a limited number of depressed cross-bars. 



Reuss's form is quite distinctive ; it differs from L. melo in the depression of 

 the cross-bars and their fewness, and from L. squamosa in the rectangular spaces 

 thus produced. Judging l)y the " Teria Nova " material. L. catciiulafct replaces 

 L. squamosa in deep-water. Very fine and typical specimens occur at Stations 16 

 and 18. less strongly marked individuals at Stations 31 and 36.
