 (after Brady.) 



Distribution. — In the Challenger material this species occurs at 

 three stations, 241, 244, 246, at 2,300, 2,900, and 2,050 fathoms, 



respectively, all in the one line of sound- 

 ings east from Japan.

Description. — Test free, cylindrical, 

 composed of a linear series of chambers, 

 variously divided into labyrinthic cavi- 

 ties; walls thick, coarsely arenaceous but 

 usually fairly smooth on the exterior; ap- 

 erture in the middle of the terminal face, 



in the early chambers simple, in the adult made up of several pores 



or dendritic. 



There seems to be but a single recent species occurring in shallow 



or medium depths usually in tropical or subtropical waters.

Description. — Test free, cylindrical or fusiform, made up of a 

 linear series of rather short chambers, usually straight; wall composed 

 of coarse sand grains neatly cemented, thick, produced in the chamber 

 and causing a labyrinthic condition; aperture in the early chambers a 

 single opening, simple, in adults becoming cruciform, dendritic or in 



° No type-species was designated by Reuss, but as his model was based upon 

 Dentalinafcedissima Reuss 1861, that may best be taken as type.
