THE NAUTILUS. 105 



Another species which bears the name of an almost forgotten 

 naturalist is Helix parraiana, Orb. D. Antonio Parra was a native 

 of Spain, and has the distinction of having written the first work on 

 Cuban fishes. This was published in 1787, the engravings being 

 made on wood by his son. His expedition was furnished by the 

 Museum of Madrid, but his work on the fishes and crustaceans was 

 printed in Cuba. 



The Loma de Camoa * is a locality which has been thoroughly ex- 

 plored, but as it can be reached in an hour from Havana on the electric 

 railway, it is impossible to pass it by. Here I collected the following 

 species: 



Oleacina oleacea, Fr. Polygyra paludosa, Pfr. 



Oleacina solidula, Pfr. Helix (Microphysa ?) stigmatica, Pfr. 



Oleacina subulata, Pfr. Cysticopsis cubensis, Pfr. 



Thysanophora vortex, Pfr. Jeanneretia multistriata, Desh. 



Thelidomus auricoma, Fer. Eurycampta bonplandi, Lam. 



Liguus fasciatus, Mull. At Cardenas this species is white, gen- 

 erally devoid of all markings, save occasionally a few green lines on 

 the last whorl. But at Matanzas less than twenty-five miles to the 

 west it is richly adorned, and like Joseph's coat, with many colors, 

 and the apex is almost invariably a rosy hue. 



Urocoptis humboltiana, Pfr. Urocoptis cyclostoma, Pfr. 



Urocoptis ischna, Pils. I am convinced that ischna is only a 

 form of cyclostoma. The smooth form is generally found in the 

 stone walls at the base of the hill, and on either side of the pro- 

 vincial road, but with it is a costate form that links it with the 

 ribbed variety. This (ischna) is usually collected on the exposed 

 cliff above where the heat of the sun would supposedly develop such 

 a protective sculpture, and a series of specimens can be laid down 

 showing the imperceptible transition from the typical and original 

 form down to the elaborately ribbed variety. 



Succinea sagra, Orb. Eutrochatella sloanei, Orb. 



Cistula catenata, Mke. Eutrochatella babei. Arango. 



Chondropoma dentatum, Say. Helicina adspersa, Pfr. 



Chondropoma pfeifferianum, Poey. Alcadia nitida, Pfr. 



Proserpina depressa, Orb., a species without operculum. 



'Zowza=hill; otherwise known as "Jamaica," and for that reason a 

 frequent occasion for confusion of localities.
