HAPLOPHRAGMOroES NIXmUM Goes. 



Haplophragmium nUidum Goes, Bull. Mus. Comp. Zool., vol. 29, 18%, p. 30, 

 pi. 3, figs. 8, 9. 



Description. — Test small, planospiral, subglobular, com])Osed of 

 two or three coils, periphery broadly rounded, somewhat lobulated, 

 last coil composed of four chambers, each of which is broad, but low, 

 either completely involute or leaving a very small but deep umbilicus, 

 wall composed of fine sand grains with much fine reddish-brown 

 cement, the surface neatly finished and with a dull luster; aperture 

 a long, narrow, semicircular slit near but not at the base of the 

 chamber, with a slight lip above and below; color reddish -brown 

 except the last-formed chamber, which may be gray. 



Diameter up to 0.5 mm. 



Distrihvtion.- — Typical specimens are from three Albatross sta- 

 tions from the Gulf of Mexico, two in the Caribbean, one off Central 

 America, the other southeast of Puerto Kico, and from two stations off 

 the coast of South Carolina. It was not found at all in the mass of 

 material north of this region. It is a small but very definite species 

 and seems to have a limited range so far as is known. 



It is very similar in form to Pullenia spJiaeroides and is another 

 case of parallelism where two species in entirely different families 

 have evolved the same form of test. The Goes material was recorded 

 from H133 in 533 fathoms (975 meters) in the Caribbean, H419 in 

 1,356 fathoms (2,480 meters) and D2392 in 724 fathoms (1,324 

 meters) in the Gulf of Moxico. There are no specimens in the Goes 

 collection returned by him to the U. S. National Museum.
