 relation to the series now represented by the 

 mogotes of "Kilometer 14." 



Having completed these four hills to our satis- 

 faction we proceeded next to the west end of Tum- 

 badero. Here we could expect only to find the 

 regulation species of the sierra unless possibly 

 we might stumble upon one or both of Wright's 

 "lost" species, a possibility that always stimulated 

 us to extra effort when in the neighborhood of 

 Vinales. Our own collecting for many miles 

 about Vinales, as a headquarters, had brought to 

 our bag many species of land-shells not noted by 

 Charles Wright, but we had never found even a 

 trace of the particular two mentioned and to 

 which he had given the simple locality designation 

 of "Vinales." To one, however, he had added 

 "En los paredones de los despefiaderos de Vinales" 

 which means "lofty unscalable places." In a re- 

 gion where there is little else than despefiaderos the 

 designation is not very positive. Wherever this 

 remarkable Blcesospira echinus does live it must be

 to distribute specimens very generally among the 

 collectors of the day. As this genus is unique
