HISPANIOLAN AND BAHAMAN ANNULARIIDAE 31 



(Chondropomium) vermicuhtum sallei. The ground color, however, is 

 much paler, and the peristome and interior of the aperture are white. 



The type (U.S.N.M. No. 354963) has 3.8 whorls remaining and 

 measures : Length, 14.8 mm. ; greater diameter, 9.2 mm. ; lesser diameter, 

 7.6 mm. 



U.S.N.M. No. 151331 contains 4 topotypes from the same source, 

 U.S.N.M, No. 354964 contains 2 specimens from the Redfield Col- 

 lection received from Cuming, undoubtedly also of Salle's collecting 

 and therefore paratypes. 



CHONDBOPOMA (CHONDKOPOMIUM) IGNOTUM, new species 



Plate 5, Figure 7 



Shell elongate-ovate, flesh-colored with almost continuous, rather 

 broad, interrupted, spiral bands of brown. The outer broadly expanded 

 peristome shows these spiral bands as rays. Nuclear whorls decollated; 

 postnuclear whorls slightly inflated, well rounded, very narrowly shoul- 

 dered at the summit and marked by retractively slanting axial riblets, 

 which grow stronger with the increase of whorls. On the last turn they 

 are very broad and separated by mere impressed lines of growth. Here 

 they have the aspect of bending over to the left, which is in reality merely 

 an optical delusion. Suture moderately constricted, not channeled; pe- 

 riphery inflated, well rounded. The base is moderately long, inflated and 

 well rounded, and marked by the continuation of the axial ribs, which 

 extend into the umbilicus. The umbilical wall is marked by strong, con- 

 spicuous, spiral cords, which increase in strength outwardly. The last 

 whorl is solute for a short fraction of a turn. The aperture is oval; the 

 peristome is double, the outer quite broadly expanded and flaring, some- 

 what sinuous; the inner moderately exserted. 



The type (U.S.N.M. No. 471940) was received from the Redfield Col- 

 lection with the locality label "Haiti?". It has three and a fraction 

 whorls remaining which measure : Length, 16.6 mm. ; greater diameter, 

 10.4 mm. ; lesser diameter, 8.7 mm,

Shell large, broadly ovate, rather heavy, marked by interrupted spiral 

 bands of brown of which the elements have their long axis parallel 

 with the axial sculpture; these elements are of irregular shape, in a 

 general way the median ones being of lunate outline, the peripheral band 

 stronger than the rest. Nuclear whorls 2, very small, forming a rather 

 slender apex, smooth, except the last portion of the last turn, which
