NO. 5 FORAMINIFERAL GENERA — LOEBLICH AND TAPPAN 21 



"wall thick, of fragments of sponge spicules and fine amorphous 

 material, the whole more or less flexible ; sutures not apparent on the 

 dorsal side, the outer portions of the chambers appearing as dark- 

 brownish areas in the general mass of grayish-white amorphous 

 material." 



When we examined the "types," the dorsal surface showed a large 

 amount of white "amorphous material," but which loosened when 

 touched with a damp brush. The original figures of the holotype 

 showed only the very highest points visible on the dorsal side, and all 

 sutures and lower portions of the chambers were obscured. The so- 

 called "amorphous material" was in fact only lime mud which had 

 not been cleaned from the specimens. A gentle cleaning with a fine 

 sable brush showed the characters to be much more like an attached 

 Trochammina. We have figured the same specimen (the holotype, in 

 fact) as is shown in the original description and in various editions of 

 Cushman's text, but there is considerable difference in the appearance 

 of the dorsal views. 



Cushman's original description mentioned only the holotype. There 

 is a single slide in the Cushman Collection which is marked holotype, 

 but on which there are two specimens. As only one can be a holotype, 

 we are assuming it to be that originally figured, and here reillustrated, 

 and the other is considered to be a paratype. 



Genus BDELLOIDINA Carter, 1877 

 Plate 3, figures 9, 10 



Orighml description. — Ann. Mag. Nat. Hist., ser. 4, vol. 19, p. 201, 



(1877). 



Type species. — Bdelloidina aggregata Carter, 1877. Original desig- 

 nation. 



Diagnosis. — Test attached, with numerous broad and low chambers 

 in a uniserial series or spreading and occasionally branching ; wall 

 agglutinated, rough externally, smooth inside with interior secondary 

 septa vertically crossing the chambers from base to top, numerous 

 internal pores pitting the interior and a row of communicating pores 

 through the septal faces; aperture a single or double row of pores 

 against the attachment on the terminal face of the last formed chamber. 



Types. — Carter's specimens have not been found but were from 

 excavations on the surface of a mass of Siderastraea, exact locality not 

 given. Brady also recorded the species from Challenger station 218 A, 

 Nares Harbor, Admiralty Islands, at 16 to 25 fathoms, and figured 

 and described the internal secondary septa which had not been noted
