FORAMIXIFERA OF THE ATLANTIC OCEAlSr.

record for the west coast of Africa I can not affirm, not having seen 

 his material. The type locality with the six closely adjacent stations 

 off our own coast certainly have the species in ty]>ical form and I 

 have examined material from hundreds of stations southward without 

 finding it, nor did I find it from the many Pacific stations examined. 

 It would seem then that we have here a very well marked s]>ecies 

 with constant characters and a comparatively' limited distribution. 



Reophax cylindricus — material examined.

Description. — -"Test elongate, cylindrical, slightly tapering, sides 

 even and unconstricted, extremities rounded. Walls thick, com- 

 posed of rather fine gray sand only partially cemented, and showing 

 no external marks of segmentation. Tlie longitudinal section reveals 

 about six segments, each tapering at the summit to a stoloniferous 

 tube, the mouth of which, as well as the external aperture of the 

 test, is stained reddish brown." 



"Length, 4/lOth inch (10 mm.) or more." 



Distribution. — The type specimens came from the cold area of the 

 Faroe Channel and a second dredging in the same area later gave 

 additional specimens, depths 530 and 540 fathoms (969 and 988 

 meters). 



The SDecimens figured by Goes under this name do not agree in 

 sha^e, in wall characters or chamber divisions with the ty[ e figures 

 and apparently represent something else. The s[)ecimens referred 

 to this species from the Caribbean by Goes^ are labeled by (voes as 

 R. ammopMla Goes in his collection returned to the United States 

 National Museum and do not seem to be R. sahulosus 11. B. Brady. 



Evidently R. sahulosus is a sr^ecies peculiar to the general region of 

 the Faroe Channel, as are other species now known nowhere else.
