by the gigantic B. maximns and Valenciennesii inhabiting the dense forests 

 of the Cordilleras with B. lacunosus and a few other allied forms. Another 

 type with shells of stout growth is represented by B. Tupacii, thamnoicus, 

 and inca ; and an extremely interesting form is presented in B. onea, found 

 by M. D'Orbigny at the bottom of a deep ravine near Tutulima. A few 

 species with delicately painted shells, constituting another group, inhabit 

 the woods in the vicinity of Cochabamba, B. linostoma, xanthostoma, 

 fusoides, etc. ; and a characteristic group with shells of light structure, 

 freely marked but not highly coloured, is typified by B. poscilus, hygro- 

 hylmts, marmarinas, oreades, etc. The ground-burrowing species, with ex- 

 tremely thin shells devoid of colour or pattern, consist of B. bacterionides, 

 lichnorum, turritella, etc. Two or three species have been collected on 

 the mountains surrounding the Lake of Titicaca, which is itself 14,000 

 feet above the level of the sea. Of these B. Pentlandi and Hamilloni 

 may be quoted as examples. In the high lands of the Cordillera range, 

 commencing at the Lake of Titicaca, passing along the region of medi- 

 cinal barks, as laid down by Weddell, to Cuzco, Chachapoyas, and the 

 Andes of Caxamarca, and extending across the equator by Quito, Bogota, 

 and Merida, nearly to Caraccas, many fine species have been collected, but 

 of too miscellaneous a variety of form to show any typical assemblages. 

 From this extensive and little-explored region we have B. labeo, Adamsoui, 

 T/wmj)soni, rhodolarynx, Hartwegii, Alto-Peruvianus, alutaceus, Tayloria- 

 nus, murrinus, LoWri, Clausilioides, and columellaris, singularly different 

 from each other, and differing altogether from the Bulimi of Bolivia and 

 La Plata. There is, however, one well-defined group inhabiting the 

 southern extremity of the Cordillera range at Merida and Bogota, of which 

 B. Cathcartia, Yeranyi, Succinoides, and quadricolor are characteristic 

 examples. They have peculiarly inflated richly coloured shells, and are 

 covered w r ith a delicate hydrophanous epidermis disposed in hieroglyphic 

 patterns after the manner of the Philippine Bulimi. 



5. Central America. 

 Of the remaining Bulimi of the American continent, about ten species 

 inhabit the central neck of land which comprises the countries Veragua, 

 Panama, Costa Rica, Nicaragua, Honduras, and Guatemala. Fourteen species 

 have been collected in the hilly parts of Mexico ; and two or three species 

 scattered in California, Texas, and Alabama, constitute the northern limit 

 of the genus in the new world. The Bulimi of Central America are very 

 distinct from those of which we have been speaking hitherto. B. Pana- 

 mensis, vexillum, translucens, and unicolor from Panama, B. comeus from 

 Real Llejo, B. discrepans from Conchagua, and B. Hondurasanus, and 

 Dysoni from Honduras, are all characterized by a thin transparent horny 

 shell of the same type. They have little pattern or variety of colour, and
