Sparingly distributed, but fairly abundant, especially at Stn. % X. The shells are 

 all thin-walled and very variable, biloculine, triloculine, and quinqueloculine speci- 

 mens all occurring, the triloculine being the most abundant.

3 Stations. 



Good examples of this compressed form of M. subrotunda occur at Stns. 2 h, 8, and 

 1 X, in company with the type. In material containing such wide variations of the 

 type-species, it appears to be desirable, for purposes of taxonomy, to separate such 

 a distinctive form.

Generally distributed and often fairly abundant. As usual, the specimens are very 

 variable, often only separable from Nuhecidaria Iradyi Millett, by the character of their 

 aperture. The best specimens were at Stns. 8, 9, 12, and % X.
