112 THE NAUTILUS. 



Caballos, a mountain some three miles to the East of Las Casas and 

 across the Casas River. 



Gundlacli visited the Island about the year 1854 and collected all 

 the species previously described and some others which were de- 

 scribed by Poey and Pfeiffer. These were: 



Chrondropoma dissolutum, Pfr., a species so near Chondropoma 

 pictum that it may be worthy of a varietal posiiion only. 



Trochatellu luteo-apicata, Poey. Trochatella callosa, Poey. 



Helix (Jeanneretiji) pityonesica, Pf'r., which so far as studied 

 does not appear to be distinguishable save, in size from the common 

 multistriata. 1 



Helix (Cysticopsis) comes, Poey (near cubensis, Pfr.). 



Glandinella (Bulimus) poeyanus, Pfr, together with a new genus, 

 Pineria, which is represented by four species only two of which 

 were described from the Isle of Pines. These were: Pineria 

 beathiana, Poey, and Pineria terebra, Poey. The latter is not 

 only one of the rarest, but also one of the most curious, of land 

 shells. 



The only addition to the fauna of the Isle of Pines since Gundlach 

 is Cerion pinerium, Dall, and a variety of this species is claimed by 

 its discoverer to be the smallest of the genus. 



It was Dr. de la Torre's hope to find some new thing in the Sierra 

 de la Canada in the interior of the Island. But this range proved 

 to be a quartz formation covered with pine trees,* which surely have 

 the right of way, so far as native vegetation is concerned, on the 

 Ishmd. The common grass of this region is Hypericum yalioides, 

 Lam. At the foot of the mountain, however, we collected 



Oleacina oleacea, Fer. Subulina octona, Brg. 



Helix (Jeanneretia) pilyonesica, Pfr. Thysanophora vortex, Pfr. 



On the Sierra de Casas we collected all the known species from 

 that locality, Urocoptls pruinnsa, Mor., rather plentifully. There 

 seemed to be two forms of this species, one which was stout and 

 large, the other much more slender, but fully as long. Near Nueva 



'The generic position of mullislrictta is still problematical, and can only be 

 definitely established by an examination of the soft parts. 



* Pinus carilKa Morelet. This tree grows also in Western Cuba, Florida and 

 the Bahamas, and until recently (1904) has been confused with Pimis cubensis 

 Griseb., the pine of Eastern Cuba.
