mSPANIOLAN AND BAHAMAN ANNULARIIDAE 177 



having 7 whorls and measures: Height, 18.6 mm.; greater diameter, 

 10.8 mm.; lesser diameter, 8.4 mm. 



U.S.N.M. No. 393015 contains 47 topotypes from the same source. 



U.S.N.M. No. 392855 contains 44 specimens taken 96 miles north of 

 Port-au-Prince. 



Since I failed to get opercula with these specimens, they must be left 

 in this uncertain position, 



INCEBTIP03IA DIFTICIIiE, new specie* 



Plate 31, Figure 3 



Shell elongate-ovate, white, with a yellowish tinge and an interrupted 

 spiral band of brilliantly reddish-brown spots on the parietal wall of the 

 deeply channeled suture. Nuclear whorls decollated in all our specimens. 

 Postnuclear whorls well rounded and marked by slightly retractively 

 curved axial riblets, of which 94 are present on the last turn. These ribs 

 render the summit of the whorls conspicuously denticulated. In addi- 

 tion to the axial sculpture, the whorls are marked by spiral threads 

 about as strong as the axial ribs, of which 13 occur on the last turn 

 between the summit and the periphery, 10 on the base, and 10+ on the 

 umbiUcal wall. The junctions of the axial ribs and spiral threads form 

 low rounded nodules. Suture deeply channeled. Periphery well rounded. 

 Base moderately long, strongly rounded, openly umbilicated. Here, as 

 well as in the umbilicus, the junctions of the axial and spiral sculpture 

 produce nodules which are even stronger than those on the spire. The 

 last whorl is solute for about one- fourth of a turn with a strong carina 

 following the posterior angle. Aperture oval; peristome double, the 

 outer moderately broadly expanded, a little more so on the inner Hp, 

 forming a moderately strong auricle at the posterior angle and marked 

 by concentric lines of growth, and backward reflected; the inner peri- 

 stome is exserted and reflected. Operculum ? 



The specimen that I have described and figured (U.S.N.M. No. 

 504147) comes from the Redfield Collection and bears the label "Lichia 

 rceveaim Pfeiffer," which of course, it is not. 



There are certain features about this shell, the moderately broadly 

 expanded and decided reflected peristome, for example, which recall 

 Licina cayemitensis. 



INCEBTIPOMA GOAVENSE, new species 



Plate 31, Figure 2 



Shell rather large and stout, pale orange-brown. Nuclear whorls de- 

 collated in all our specimens. Postnuclear whorls strongly rounded, 

 marked by strong lamellar, almost vertical axial ribs, of which 122 are 

 present on the last turn. The spiral sculpture consists of strong threads, 

 of which 12 are present between the summit and the periphery of the
