BULLETIN 104, UNITED STATES NATIONAL MUSEUM. 



Distribution. — Type specimen (U.S.N.M. No. 10081) from Albatross 

 station D2383 from the Gulf of Mexico. It occurs at several stations 

 in this area, the following being recorded by Flint in addition to those 

 given here, D2382, D2398, and D2400, all in the Gulf of Mexico. 



This is much larger than typical H. ovicula, and 1 am not sure but 

 that much if not all of the material placed under //. ovicula from the 

 Gulf of Mexico had not better be placed here. It is very different 

 from northern typical H. carpenteri when the two are seen together. 

 It is worthy of note that the specimens in the Goes collection are 

 labeled b}^ him "H. ovicula var. carpenteri," evidently showing his 

 indecision as to which of these two species to assign his specimens 

 when he labeled them.

Hormosina monile H. B. Brady, Quart. Journ. Micr. Son., vol. 21, 1881, p. 52; 

 Rep. Voy. Challenger, Zoology, vol. 9, 1884, p. 328, pi. 39, figs. 10-13. 



Description. — Test composed of numerous subglobular chambers, 

 of nearly equal size in a straight or somewhat irregular series; wall 

 finely arenaceous, firmly cemented, fairly smooth on the exterior 

 except for the ends of sponge spicules protruding from the wall; 

 color light ruddy brown. 



Length up to 6 mm. 



Distribution. — Brady's only record for this species is Cliallenger 

 station 122 off Pernambuco, Brazil, in 350 fathoms (640 meters). 

 The material I have here referred to this species is not found at any 

 of the stations in any considerable numbers, that from the Leeward 

 Islands being the most nearly typical.
