Miliolidae 

 QuiNQUELOCULiNA d'Orbigny 



Q. FuscA H. B. Brady. North Pacific specimens of this form 

 have been figured recently by Ciishman which agree well ^\nth 

 ours. The species was hitherto unknown from the western 

 Atlantic. The general color of the dry test is pale dust-brown. 

 Found on sand and blue clay from the shore to 210 feet. 



Stations : S 21, 25, 48 ; D 19, 150. 



Q. SEMINULA (Linne). On muddy sand, gravel, and blue 

 clay, from the shore to 210 feet, abundant. 



Stations : S 21, 25, 48 ; D 19, 62, 76, 83, 150. 



Q. VENUSTA (Karrer). Our form is figured by Flint (1899, 

 pi. 44, fig. 2). Doctor Cushman does not consider it certain 

 that Q. fusca of authors is Karrer 's species. On muddy sand 

 and blue clay, from shore to 210 feet, only one specimen on 

 blue clay from D 150. 



Stations: S 21, 25; D 76, 150. 



Massilina Schlumberger 



M. SECANS (d'Orbigny). This is M. secant of authors, but 

 according to Doctor Cushman probably not d'Orbigny 's form. 

 It is new to New England. On mud, sand, and blue clay from 

 the shore to 239 feet, not common. 



Stations: S 48, D 19, 126, 130. 



TRnjOCULiNA d'Orbigny 



T. OBLONGA (Montagu). The single specimen is 0.46 mm. 

 wide. The 2 last-formed chambers each show 3 or 4 faint 

 longitudinal furrows. On blue clay, depth 239 feet. 



Station: D 130. 



Pyrgo Defrance 



This is a difficult genus of which we have had specimens 

 representing about 5 species. The determinations of the 2 

 species given below are by no means certain. It is worth 

 noting that the specimens are not bilaterally s^Tnmetrical in 

 ventral view owing to the slightly excentric position of the 

 penultimate chamber.
