Universally distributed and often abundant, but never attaining any large size or 

 development. The best specimens at Stn. 3. At Stns. 9 and 12 the specimens were 

 large and showed signs of superficial markings linking the species with M. striata.

5 Stations. 



Very poorly represented in the material ; all the specimens differ somewhat from 

 Keuss's figure in having a produced neck, and are, perhaps, more related to the allied 

 M. lucida (Karrer), which is cited by Brady as a synonym of Reuss's species. 

 According to Brady the species is a rather deep-water form. 



51. Miliolina exsculpta, sp. n. (PL XLII. figs. 23-26.) 



6 Stations. 



Test free, minute, thin-walled, often opalescent, having three chambers visible on 

 one face and four or more on the other. Sutural lines deeply excavate and undercut, 

 especially at the extremities of the shell. Chambers embracing, and crescentic in 

 section, the individual chambers being narrow at the oral extremity and very broad 

 and embracing at the aboral end of the shell. Furnished with a somewhat produced 

 neck, sometimes lipped, and terminating in a toothless aperture regularly and constantly 

 crescentiform. Surface highly polished, peripheral edges rounded. The chambers are
