CANARIAN GROUP. 431 



Habitat Canariam Grandem ; in sylvis editioribus ad Osorio 

 a Eevdo. R. T. Lowe, Aprili 1858, parce lectus. 



Although without any very conspicuous feature to charac- 

 terise it, this little Bulmius certainly cannot be affiliated with 

 any of the forms with which we are here concerned, — perhaps 

 its unusually small size, as compared with the generality of 

 these robust, barrel-shaped species, constituting one of its 

 main peculiarities. Apart from its reduced stature, the B. 

 osoriensis is narrower and less obtuse in outline than the 

 Teneriffan B.nanodes (which is likewise a small member of the 

 group), its spire, the whorls of which are rather inflated and 

 convex, being relatively a little more exserted and conical ; its 

 umbilical chink is more closed-up ; and its entire surface is not 

 only more shining, but free from asperities and granules, — it 

 being simply, though unequally, striated. 



It is only in the sylvan regions of Grand Canary, at a high 

 altitude, that the present Bulimus has hitherto been observed, 

 — the few examples which I have seen, and from which the 

 above diagnosis has been compiled, having been taken by Mr. 

 Lowe, on the 24th of April 1858, in the woods at Osorio. 



Bulimus chrysaloides, n. sp. 



T. aperte rimata, obtuse oblongo-cylindrica, solida, subopaca, 

 valde irregulariter necnon in anfractibus intermediis (sensim 

 elongatis) rugosius subgranulatim striata, olivaceo-cornea ; spira 

 subconico-cylindrica ; anfractibus 7, planiusculis tamen sutura 

 profunde impressa ; apertura angusta, hand obliqua, peristo- 

 mate albo, vix late expanso, marginibus distantibus (nee ap- 

 proximatis) et lamina tenui (ad insertionem dextram paulum 

 incrassata) junctis, columellari sat reflexo. — Long. lin. 6 ; 

 diam. maj. vix 3. 



Bulimus chrysaloides, Loive, in litt. 



Habitat Canariam Grandem ; in montibus centralibus valde 

 elevatis (sc. in Pineto de Tarajana), Aprili ineunte 1858, 

 collegit Eevdus. E. T. Lowe. 



The present species, like the last one, seems to be peculiar 

 to Grand Canary, where it would appear to ascend to a still 

 liigher altitude, — the only examples (five in number) which I 

 have met with having been taken by Mr. Lowe (on the 8th and 

 9th of April, 1858) in the lofty Pinal of Tarajana, above San 

 Bartolome, in the central district of that island. 



Its obtuse and unusually cylindric contour would of itself 

 suffice to separate the B. chrysaloides from the Bulimi with 

 which it is immediately associated ; but it may be further known 

 by its somewhat flattened volutions, the intermediate ones of
