93 



Type-specimen. — Cat. No. 8261, U.S.N.M., from Albatross station

 in Bering Sea. 



REOPHAX CATENULATUS, new species. 



Description. — Test consisting of a series of subglobular chambers 

 of large size connected by rather slender tubular portions, walls of 

 coarse sand grains very roughly cemented, 

 color gray or yellowish-brown. 



Length of three chambers, 7 mm. ; diam- 

 meter of largest chamber, 1.8 mm. 



Type-specimen.— -Cat. No. .8262, U.S.N.M. ,

Genus HORMOSINA H. B. Brady,

 B. Brady), Quart. Journ. Micr. Sci., vol. 19, 

 1879, p. 56. — Butschli, in Bronns Klassen 

 und Ordnungen des Thierreichs, vol. 1, 1880, 

 p. 199.— H. B. Brady, Rep. Voy. Challen- 

 ger, Zoology, vol. 9, 1884, p. 325. 



Description.— Test free, composed of a 

 series of subglobular, fusiform or pyriform 

 chambers joined end to end in a single 

 moniliform series, walls thin, finely arena- 

 ceous, chambers undivided, aperture a single 

 circular opening at the distal end of the neck 

 of the chamber, color brownish. 



This genus differs from Reophax mainly 

 in its fine texture, smooth surface, and 

 brown cement. Several species occur in 

 the North Pacific, but usually in fairly deep water.
