POEAMINIFEEA OP THE KEEIiMBA AECHIPELAGO. 625 



Stns. 7 and 10 all devoid of a produced phialine aperture, but presenting the well- 

 marked concavity down the naedian line and the quadrangular section with rounded 

 periphery distinguishing the species. The Kerimba specimens are much nearer 

 Fornasini's figure (F. 1903, TA.) than Karrer's original drawing. At Stn. ] X one 

 specimen was found of the variety figured by Brady (FC. pi. xliii. fig. 11) which he 

 regarded as a passage-form linking the species with T. gramen.

Very sparingly distributed. The best at Stn. 1 X, where the specimens are quite 

 typical and identical with de Blainville's figure. At Stn. 9 it occurs in two well- 

 marked varieties, characterized respectively by broad and narrow shells, but the 

 characteristic parallel sutural lines are distinctly marked in both varieties.

Occurs at very few Stns., but when present is usually abundant and characterized by 

 an extraordinary range in size aud variety in the relative proportions of the length and 

 breadth of the test. Stn. 11 furnishes a numerous and typical series ranging from 

 the very short and broad, strongly limbate form figured by Millett {ut su.pra) to the 

 long variety figured in the Crag Monograph. The short thick type with less 

 conspicuous limbation separated by Fornasini as the " abbreviated form " also occurs 

 at this Stn.
