FORAMINIFERA OF THE ATLANTIC OCEAN. 



29 



Distribution. — Tlie records for this species are not numerous. In 

 the North Atlantic Brady had one or two specimens only from a 

 single station off the American coast at about 40° N. latitude. It is 

 also recorded from a Challenger station off Culebra Island, West 

 Indies, and at two stations oft' the coast of South America. Flint 

 records it from the southeastern coast of the United States and from 

 the Gulf of Mexico. Goes records it from the Gulf of Mexico and 

 the Caribbean. 



The only east coast specimens I have seen are from D2505, off 

 Nova Scotia. The remainder of the specimens are all from the 

 Gulf of Mexico and the Caribbean Sea. The Gulf of Mexico stations 

 are from the same or adjacent stations to those from which Goes 

 and Flint recorded the species. The single Caribbean station, 

 D2140, is from south of Jamaica, the material in the Goes collection. 



In form and coloration this species is weU marked. It is perhaps 

 nearest to H. carpenteri, but is usually straight, where H. car'penteri 

 is usually irregular and crooked and of much larger size. In the 

 Gulf of Mexico, however, the species often has a coating of fine 

 gray material and occasionally sponge spicules resembling the 

 exterior of H. carpenteri. Flint's figured specimens show this 

 character; also the more rounded chambers which the specimens 

 from the Gulf of Mexico often have.
