2 Stations. 



A few small specimens at Stn. 11 characterized by coarsely agglutinate tests, 

 and a few at Stn. 13 in which the test is larger and constructed of very fine material.

A single abnormal specimen from Stn. 1 X, which we figure. It is characterized 

 by the fact that the early portion of the test consists of five or six pairs of regularly 

 textularian chambers, followed by seven chambers of the normal uniserial type. The 

 aperture is regularly clavuline. The shell is built up of extremely fine clear sand- 

 grains, glistening white in colour. The sutural lines of the later textularian chambers 

 and most of the uniserial chambers are marked by a somewhat thickened deposit of 

 granular texture. The test is curved at the point of transition from the textularian, 

 to the uniserial mode of growth.

Ranges from extremely rare to common, but not universally distributed. The best 

 specimens were at Stns. 2 a and 7. There is great range in the shape and nature of 

 the test ; in some instances it is coarsely built of sand and shell-fragments of dis- 

 proportionally large size, the segmentation being quite obscure ; in others the sandy 

 grains are small and the proportion of cement large, resulting in a neatly constructed 

 test with well-marked sutural lines.

1 Station. 



A single specimen in which the final chamber is separated from its predecessors by 

 a somewhat deep suture and occupies one-half of the entire shell.
