80 BULLETIN 104^ UNITED STATES NATIONAL MUSEUM. 



Description. — Test attached by the proloculum which is bulbous, 

 remainder of test tubular, of nearly uniform diameter, irregularly 

 dichotomousiy branching, wall composed of fine sand grains with an 

 abundance of reddish-brown cement; apertures at the ends of the 

 tubes. 



Length, up to 5 mm. 



Distribution. — On the eastern side of the Atlantic there are numer- 

 ous records for this species. In the Arctic it is recorded from off 

 Greenland, Iceland, Nova Zembla, Franz Joseph Land, and north of 

 Siberia; off the coasts of Norway and Great Britain, and in the 

 South Atlantic off Pernambuco, Brazil. 



On the western side of the Atlantic this species seems to be either 

 missing or overlooked. In the Albatross dredgings broken specimens 

 have occurred which might have been assigned to this species but 

 never sufficiently weU preserved to make identification sure. 



In Europe it usually occurs in comparatively shallow water, 200 



fathoms being the shallowest. Off Brazil it was recorded at 350 



fathoms.

 Rhumbler, Arch. Prot., vol. 3, 1903, p. 272. 



Description. — Test with a subglobular proloculum, with a sub- 

 cylmdrical second tubular chamber more or less definitely con- 

 stricted at intervals but the interior not completely septate; wall 

 composed of sand grains and fragments of spicules with a large 

 amomit of calcareous (?) cement; open end of the tubular chamber 

 serving as the aperture. 



This genus was erected by de Folin for the following species: 



KALAMOPSIS VAILLANTI de Folin. 



Kalamopsis vaillanti De Folin, Congrfes Scient. Dax., 1882, p. 320; Act. Soc. 

 Linn. Bordeaux, vol. 40 (eer. 4, vol. 10), 1886, p. 288, pi. 8, figs. 12a-c.— 

 Rhumbler, Arch. Prot., vol. 3, 1903, p. 272, fig. 121 (in text). 



Description. — ^Test with a bulbous, subglobular proloculum, fol- 

 lowed by a second chamber, subcylindrical, tubular, more or less 

 regularly constricted on the exterior, the portions thus formed sub- 

 conical, the widest portion at the basal end; wall composed of sand 

 grains, fragments of spicules, and large proportion of calcareous ( ?) 

 cement; outside smooth except for occasional sand grains, interior 

 smooth except at the constricted areas, where there are slight in- 

 wardly projecting portions of the wall slightly obstructing the tubular 

 chamber at irregular intervals; aperture formed by the open end of 

 the tube; color greenish gray. 



Distrihution. — This species was described by de Folin from the 

 GuK of Gascony and lias not been recorded elsewhere.
