was met with by Mr. Lowe and myself on the Cnmbre above 

 Buenavista, as well as by the edges of the Vueltas on the 

 ascent to that elevated region ; and it would appear to have 

 been found also by Blauner.

Habitat Palmam ; in sylvaticis humidis editioribus, rariss., 

 una cum P. Pompylia, ShuttL, degens. 



Like the P. Pompylia, Shuttl., the P. textilis occurs in the 

 higher and wooded districts of Palma, — to which island (unless 

 indeed the P. concinna, Lowe, from Hierro, be but a local mo- 

 dification of it) it would seem to be peculiar. It is evidently, 

 like that species, of the greatest rarity, but was met with 

 by Blauner, and subsequently both by Mr. Lowe and myself 

 (during June, 1858), on the ascent of the Cumbre above Buena 

 vista. 



Although possessing much the same character of sculpture, the 

 P. textilis may at once be known from the P. Pompylia by its 

 larger size, its just perceptibly more elevated spire, and its 

 very much wider and more open umbilicus. Its basal volu- 

 tion, too, is relatively a trifle broader or more developed ; 

 and its transverse costae are conspicuously more oblique.

Habitat Hierro ; in regione sylvatica ' El Golfo ' dicta, sub 

 cortice truncorum putrescentium, a meipso inventa. Forsan 

 pnecedentis status insularis. 



I am extremely doubtful whether this is anything more 

 than an insular modification, peculiar to Hierro, of the Palman 

 P. textilis ; nevertheless since it has a few very minute cha- 

 racters of its own, and it was enunciated as distinct by Mr. 

 J* nve, I will not attempt absolutely to amalgamate the two. 



Judging from the five types which are now before me,
