E. chrysochasma jucunda ("Gund." Pfr.) (1863). 



??E. chrysochasma hernandezi "Wright" A. J. Waguer (1908). 



E. mestrei Arango (1878). 



Section Cubaviana new section. W. Cuba. 

 Type //. politula Poey (1852). Santa Cruz, Cuba. 



The radula of the type of this section has been described and 

 figured by Troschel (1856-63). I have re-examined it 45 and also 

 E. pyramidalis 4 *; the T-lateral of the former figured (Plate VI, 

 fig. 33). The radular formulae of both species are given in Table 

 IV. 



The centrals of this section are not quite so definitely cusped as 

 in the preceding group, but are very similar. The T-central 

 has only a few scallops and points near the outer edge of the margin. 

 The A-plate, not shown by Troschel, is very similar to that in 

 Troschelviana s. s. 



The shells of this section are not quite so elevated as in the 



preceding group, but are more nearly conical in shape. They 



agree with it in the poor development of the spiral sculpture. I 



think that probably the following species belong here: 



E. methfesseli (Pfr.) (1862). 



E. straminea straminea (Morelet) (1851). 



H. exacuta Poey (1852). 

 E. straminea rubromarginata ("Gund." Poey) (1856). 

 E. straminea festa (" Gund. "Sowerby) (1866). 

 E. straminae nodae (Arango) (1862). 

 E. straminea politula (Poey) (1852). Type. 

 E. fuscula ("Gund. "Pfr.) (1863). 

 E. cisnerosi (Arango) (1878). 

 E. wrighti wrighti (Pfr.) (1863). 

 ??E. wrighti xanthacme A. J. Wagner (1911). 

 E. elongata (d'Orbigny) (1845). 

 E. pyramidalis pyramidalis (Sowerby) (1842). 

 E. pyramidalis percarinata A. J. Wagner (1908). 



//. arnica d'Orbigny (1845), not Pfr. (1839). 

 ??E. scopulorum (Morelet) (1849). Isle of Pines. 



//. luteopunctata Poey (1852). 



H. luteoapicata Poey (1854). 



Subgenus PYRGODOMUS C. and E. Cuba to Guatemala; Bahamas? 



Pyrgodomus Crosse and Fischer (1893). Type (monotype) H. chryseis 



Tristram (1861). Guatemala. 

 Artecallosa A. J. Wagner (1908). Type (now chosen, as used as Pyrgodomus) 



H. chryseis Tristram (1861). Guatemala. 

 ? Callida A. J. Wagner (1908). Type (by tautonomy) H. calida Wein- 



land (1862) (E. callida A. J. W.). Not Callida "Dejean" Leconte 



(1859). 47 



45 2 dried specimens; A. N. S. P. no. 15170; Rangel, Cuba. 



16 3 dried specimens; A. N. S. P. no. 14885; southwestern Cuba. 



47 This group may belong to Eutrochatella s. s., but the size of the shell and its 

 shape look more like this subgenus. I do not think the name can be used, altho 

 L'alh.ida Dejean (1825) appears to be the original spelling of the genus in Cole- 

 optera
