Avhoii nine) strong rounded ribs, feeble on the fasciole and reaching 

 to the canal; aperture narrow, anal sulcus deep with a small sub- 

 sutural callus; outer lip arcuate, prominently varicose, the edge in- 

 folded; inner lip and pillar smooth (possibly not quite adult); 

 canal short, distinct, slightly recurved. Height of shell, 10; of last 

 whorl, 5 ; diameter, 4 mm. Cat. No. 195004, U.S.N.M.

 coral sand, surface temperature 81° F. U. S. Bureau of Fisheries. 



This species is small for the genus and perhaps has not quitie com- 

 pleted the callosities around the aperture. 



GLYPHOSTOMA CYMODOCE, new species. 



Plate 17, fig. 6. 



Shell small, flesh colored, slender, acute, with a smooth small pur- 

 ple-brown nucleus of about two whorls and about six subsequent 

 whorls; suture appressed with a slightly constricted fasciole immedi- 

 ately in front of it sculptured by half a dozen fine sharp close- 

 set equal spiral threads; other spiral sculpture of (on the spire two to 

 four) flattish spiral major cords with equal or wider interspaces in 

 wdiich runs an intercalary smaller thread; on the last whorl this 

 sculpture is continuous over the shell from the shoulder to the base, 

 but the intercalary threads gradually enlarge until they are prac- 

 tically equal to the originally larger cords; the small siphonal fas- 

 ciole has a few finer and closer threads; axial sculpture of (on the 

 penultimate whorl about eleven) rounded vertical ribs extending 

 from the shoulder to the succeeding suture, but obsolete on the last 

 whorl and not nodulose where they are intersected by the cords ; the 

 incremental lines are only conspicuous on the anal fasciole, wdiere 

 they are slightly puckered in front of the suture ; aperture subovate, 

 anal sulcus deep, rounded, close to the suture with a subsutural 

 callus; outer lip thickened, slightly crenulate by the external sculp- 

 ture, smooth within, arcuately produced, with a prominent varix 

 behind it; inner lip erased, pillar short, canal short, distinct, slightly 

 recurved. Height of shell, 11.5; of last whorl, 6; diameter, 4 mm.

PHILBERTIA HESIONE, new species. 



Shell small, whitish, biconic, acute, with a smooth bulbous nucleus 

 of a whorl and a half and four and a half subsequent sculptured 

 whorls; suture distinct, not appressed, the anal fasciole close to it, 

 flattish, at first w^ith fine spiral sculpture but on the last whorl it 

 becomes nearly smooth: other spiral sculpture of a narrow prominent 

 thread at the periphery which is doubled on the subsequent turns, on 

 the last whorl there are ele^•en of the threads which are somewhat
