overhano:iaij; portion of the ^vall sli<j:litly extended, forminji' a thin 

 lip; color a grayish brown, the last-formed chamher often more 

 i^ray than the preceding ones. 



Diameter, 0.75-1.5 mm. 



Distribution. — This species from the synonymy given a1)ove 

 will ])e at once seen to have been i-ecorded by many wiitei-s from 

 widely distant areas. Evidently, from a comparison of figures 

 referred to thi-; species, there is a considerable rang<> in form, size, 

 and general chara<'ters or else more than (me species is included under 

 this name. Tiie ori(2;inal figure given by d'Orlugny is very close to 

 one species foinid in comparatively shallow watei- off our Atlantic 

 coast, and to this the name //. canarieiisis is here restricted. As the 

 other records are ])ased on a loose application of the name, no 

 attempt is here made to straighten out the problem, which can only 

 be accomplished by a study of the actual specimens. However, it 

 may be noted that of Brady's figures plate 35. figin-o 1 , is very close to 

 the material from the western Atlantic. 



All seven stations from which material was obtained are between 

 37° and 40° N. latitude and 71° and 75° W. longitude. I have 

 also found it in shallow-water material ofT the New England coast 

 in my own dredgings,

Plate 8, %. G. 



Description. — Test planospiral, involute, umbilicate, com])osed of 

 about three coils, periphery broadly rounded, slightly lobulate, 

 usually nine chambers in the last coil of adult specimens, sutures 

 distinct: wall coarsely arenaceous, surface fairly smooth, aperture 

 an elongate semicii-cular slit at the base of the final chambei-, the 

 upper portion forming a thin lip; color gray or light brown. 



Diameter.-~Ty\)e specimen (U.S.N.M. No. 10675a) from Alba- 

 tross D2453 in the Gulf of St. Lawrence in 82 fathoms (150 meters). 

 It also occurred south of Newfoundland on the Grand Banks and 

 at four stations south of Marthas Mnevard and Nantucket, all at
