CHONDROPOMA (CHONDROPOMORUS) 8AL,L,EANUM COOKEI, new subspecies 



Plate 1, Figure 8 



The type (U.S.N.M. No. 491999) was collected by Dr. C. W. Cooke 

 at U. S. Geological Survey station 8597 on a limestone hill south of 

 Hatillo, 12 miles southwest of Cotui in the Province of La Vega, 

 Dominican Republic. It has 6.9 whorls and measures: Length, 15.2 mm.; 

 greater diameter, 8.6 mm.; lesser diameter, 6.9 mm. U.S.N.M. No. 

 472000 contains 4 topotypes from the same source. 



Its much smaller size will at once distinguish this race from Chondro- 

 poma (Chondropomorus) salleanum salleanum.

Shell broadly conic, with flesh-colored or faintly brownish ground 

 color, the summit of the first nuclear whorl being dark reddish brown; 

 the first postnuclear whorl with four interrupted spiral brown bands, 

 the dots forming these bands having their long axis parallel with the 

 spiral sculpture and being arranged in both axial and spiral series. On 

 the next turn these bands break up into irregular-shaped elements, 

 which on the succeeding turns form axial series of more or less zigzag, 

 fulgurated, or flammulated markings. There is a zone of comma-shaped 

 marks near the summit and a more or less conspicuous spiral band of 

 small, rectangular, rather distantly spaced spots at the periphery; a 

 little less conspicuous one paralleling this is a little posterior to the 

 periphery, and a second band a little anterior to the periphery is made 

 up of very large squarish spots. On the base there are two other bands, 

 one continuous and marking the outer limit of the umbilicus, the other 

 a little nearer this than the subperipheral large spots. The inside of 

 the aperture shows these bands conspicuously and so does the outer lip 

 of the peristome, while the inner lip is less conspicuously marked. 

 Nuclear whorls a little more than 2, forming a truncated apex ; all are 

 rounded and smooth except the last portion of the last turn, which 

 shows a few fine axial threads. The postnuclear whorls are strongly 

 inflated, well rounded, and marked by rather closely crowded, low,
