CHONDBOPOMA (ABTICITLIPOSCA) CABOLI, new species 



Shell of medium size, broadly ovate, flesh-colored, with spots and 

 dots and sometimes fulgurations of varying sizes of chestnut-brown and 

 arranged more or less in spiral and axial series. A series of these brown 

 spots, much larger than the rest, is present immediately below the sum- 

 mit. The peristome may be rayed or unicolor. Nuclear whorls almost 2, 

 inflated, strongly rounded, smooth except the last portion of the last 

 turn, which shows the beginning of the postnuclear sculpture. The post- 

 nuclear whorls are decidedly inflated, strongly rounded, narrowly 

 shouldered at the summit, and marked by rather strong, well-rounded, 

 slightly retractively curved axial riblets, which are almost as broad 

 as the spaces that separate them. These ribs are strongest developed 

 near the summit, where small groups of three or more project above an 

 equal or slightly larger number, which are a little shorter. This gives to 

 the summit of the whorls a tufted effect, but the ribs do not become 

 fused at the summit here, as they do in Chondroponiorus, but remain 

 distinct. The projecting ones are usually heavier than the shorter ones, 

 forming the interval between them. The spiral sculpture consists of 

 quite low, broad, rounded tumidities. I use this term to distinguish them 

 from true cords, for they hardly have the aspect of a cord. It is these 

 tumidities that render the axial ribs vertebrated at their junctions. The 

 narrow tuberculated summit renders the suture almost channeled. Pe- 

 riphery inflated, very strongly rounded. The base is short, inflated, 

 strongly rounded, sculptured like the spire. The open umbilicus shows 

 the continuation of the axial ribs on its wall and a series of rather 

 strong spiral cords. The last whorl is solute for a varying distance in 

 the different races. Aperture broadly ovate. Peristome double; the outer 

 auriculated at the posterior angle, broadly expanded on the outer and 

 basal lip as well as on the anterior half of the columella, where it 

 attains its greatest width ; it is narrower on the parietal wall. The inner 

 peristome is decidedly exserted and slightly reflected. Operculum thin, 

 paucispiral, with the nucleus halfway between submarginal and sub- 

 central, covered on the outside with scattered calcareous granules. 



This species was collected by Charles Russell Orcutt, for whom I 

 take pleasure in naming it. He found one race at Bodarie on the trail 

 between Fonds Verettes and Saltrou, and another on Gimbi Mountain 

 on the trail between Saltrou and Croix des Bouquets, Haiti. 



The following key and descriptions will help to distinguish the two 

 subspecies :
