712 MESSES. E. HEEON-ALLEN AND A. EAELAND ON THE 



T. echinata is an extremely anomalous form, and its allocation to the genus Trunca- 

 fjulina rather than to Sphceroidina (to which in our opinion it has considerable 

 affinities) must be based chiefly on the occurrence of anomalous specimens, in which 

 the truncatuline features predominate. We would direct attention to Egger's figures 

 and description, which represent compressed individuals much more closely allied to 

 2\ reticulata than to the type. 



The Kerimba specimens illustrate practically all variations of the globular type, 

 from tests covered with a few large blunt tubercles, through roughly spinous to prac- 

 tically smooth individuals with thick and coarsely perforated shells. At most Stns. 

 a distinct type occurs, which we have separated under the specific name T. glabra 

 (q. V. ante). 



At Stn. 3 a double specimen, which we figure, was found ; it appears to be due to 

 the fusion of two individuals either at the primordial stage or, perhaps, at a slightly 

 later stage of growth. The individuals have preserved their separate apertures. 



It seems probable that the figures given by Carpenter in 1860 (C. 1856 etc., EF. 

 1860, p. 551, pi. xix. figs. 5 and 1 6) and described as " young Calcarinse showing 

 their ordinary aspect" represent this species." They suggest it far more than they do 

 Calcarina.

Two large and extremely typical specimens at Stn. 11. The occurrence of these 

 individuals in this dredging, made in very shallow water, and the entire absence of 

 the species at the other Stns., some of which present a more favourable depth, is 

 noticeable,
