common than the typical form. It has occurred at several stations 

 in the Albatross collection from the Gulf of Mexico and oil the 

 Florida coast. Brady recorded this species from off Culebra Island, 

 West Indies, 395 fathoms (721 meters), and from off Bermuda, 435 

 fathoms (79G meters). Flint has recorded it at 198 and 210 fathoms 

 (363 and 384 meters), at stations D2399 and D2377, from both of 

 which I have also had material. The records of Goes are from the 

 Caribbean, 300-400 fathoms (549-732 meters). It seems therefore 

 to be a species confined to the warmer portions of the western At- 

 lantic and which is ' developed at depths ranging from 100-400 

 fathoms (183-732 meters). 



The microspheric form of this species has the chambers arranged 

 in a coiled fashion and in such specimens a much more pointed form 

 is usually given to the base of the test. This is shown in some of 

 the early figures given by Goes, and is here shown, plate 21, figure 1. 



This does not seem to be identical with the form named by D'Or- 

 bigny, FrondiculaHa alata, from the Mediterranean.

I have a single specimen of a peculiar species of Frondiculana 

 from Albatross station D2192, off the northeastern coast of the 

 United States, in 1,060 fathoms (1,938 meters). It is here figured. 



The surface has costae which stand above the general surface of 

 the test and which are sharp and plate-like. No other Atlantic 

 specimens were obtained.
