SAIXT HELENA. 547 



suspect that too great reliance must not be placed upon the 

 latter characters, -the breaking-away of the aperture tending 

 usually (to say nothing about the consequent destruction of the 

 peristome) to cause the columella to appear more elongated than 

 it really is. 



Prof. Forbes speaks of the B. Blofeldi as nearly allied to a 

 recent undescribed species which was ' found by Mr. Alexander 

 feeding on the Cabbage-Trees on the highest points of the 

 island.' I am totally unaware of any living Bulimus on so 

 large a scale at St. Helena ; but when re-detected, and charac- 

 terized, it will doubtless constitute a most significant addition 

 to the fauna. If Forbes was really acquainted with it, as his 

 remarks would almost imply, why did he not publish a descrip- 

 tion of it, and give us the advantage of a figure ? Perhaps it 

 may be absolutely identical with the Blofeldi, and with the 

 species which was wrongly referred by Eeeve to the B. helena, 

 Quoy. 



The B. Blofeldi appears to have been met with by Mr. J. 

 H. Blofeld, in company with the (equally subfossilized) Helix 

 bilamellata, in a reddish clay or loam, in a cutting of the 

 ' Sidepath Road ' (which leads from Jamestown to Longwood) 

 overlooking the ' Briars,' — at an elevation of about 1200 feet 

 above the sea. 



(§ Paehyotus, Beck.) 

 Bulimus auris-vulpina. 



T. magna, crassa, ovato-conica, aperte rimata, densissime 

 transversim (i. e. longitudinaliter) striata (striis inaequalibus, 

 subconfluentibus), plerumque albida ecolorata sed in exemplari- 

 bus bene conservatis pallide corneo- et albido-nebulosa ; spira 

 conica ; anfractibus 7, antice (i. e. pone suturam grosse crena- 

 tam), prsecipue in ultimo, sub-biangulatis et spiraliter subnodu- 

 losis; columella contorta; apertura angustula, auriformi, peri- 

 stomate subreflexo, incrassato, canaliculato, margin ibus callo 

 robusto junctis, dextro sinuato (sc. intus ssepius dilatate pro- 

 minulo), columellari late reflexo. — Diam. maj. 13; long. 22- 

 23 lin. 



var. ft. subspiralis [an species vera ?]. — Obtecte rimata ; 

 anfractibus minus longitudinaliter striatis sed obsolete, parce, 

 et obtuse spiraliter costatis ; callo ventrali longe intus in medio 

 tuberculato-gibboso. 



var. 7. obliteratus. — Obtecte rimata ; anfractibus antice 

 etiam obsoletius biangulatis ; peristomate minus incrassato, 

 margine dextro fere simplici (i.e. intus vix ampliato) ; callo 

 ventrali longe intus in medio leviter tuberculato-gibboso.
