BrLDlLS.— Plate XVIII. 



(Jf this vcn- cliaraclovistic and pretty species, collected 

 in perfection bv Mr. Bridges, M. D'Orbigny found but 

 two dead specimens in a damp ravine near the banks of 

 the Rio San Mateo, Coehabamba, Bolivia, on the North- 

 Kast side of the Eastern Cordilleras. It is chiefly re- 

 markable on account of the patulate effused formation of 

 the ajjcrturc and deep rose-purple stained columella.

llnli. Truxillo, Peru (on bushes on the mountains) ; 

 Cuming. 

 Though appro.ximating very closely to the li. varimis, 



there is a sufHcient variation in the form of this species to 



render it distinct ; the body-wiiorl is of greater length 



and the aperture more effused.

 IM. Tutulima, Bolivia. 



It is entirely owing to the enterprising spirit of M. 

 Alcide P' Orbigny that we arc indebted for the knowledge 

 of this beautiful species. " Desiring to find a more im- 

 mediate communication," says that intelligent traveller, 

 "between Cochabiunba and Moxas, Bolivia, we made a 

 proposition to the Goveniment of that Republic to make 

 the attempt. The President, General Santa Cruz, furnished 

 us with the means to achieve this undertaking. We set 

 out on foot with a party of Indians to carry proTOioiis, 

 and after passing forty days amid the precipices of unin- 

 habited mountains on the north-east side of the Eastern 

 Cordilleras, and enduring a thousand difliculties and pri- 

 vations we accomplished our journey. It was in this 

 excursion not far from Tutulima that we observed the 

 liidimus onca at the bottom of almost inaccessible ravines 

 in damp woody situations, where it is of rare oeeun-ence 

 and ditlicult to procure, from its habit of burying itself in 

 the earth."
