8 KOBELT : ON THE LAND SHELLS OF GIBRALTAR. 



allied to the Sicilian group, globularis, platycheila, &c. 

 At the Monkey Mount and the Sierra Bullones kindred 

 forms might no doubt be found. 



12. Helix (Pomatia) aspersa Miiller. 



In masses in the rock fissures on the road to Signal 

 Point, probably also in other parts. The color in 

 these is very dark. 



13. Helix (Euparypha) pisana Miiller. 



Very numerous upon windmill flat and Europa 

 Point, also higher up on the rock. 



14. Helix (Heliomanes) sp. 



In the low-lying ground between the Rock Gun 

 and Signal Point I found a Xerophile in great numbers

 form I found later on near Algesiras, I am not certain, 

 and defer the determination in the meantime. 



15. Helix (Turricula) simiarum m. 



Testa depresse conoidea, anguste sed profunde um- 

 bilicata, subtiliter regulariterque costulato-striata, alba, 

 fascia latiore suturati castanea suturam in spirant 

 sequente super peripheriam nonnuUisque mimis distinctis 

 ad basin ornata. Anfr actus j" — 6 parum convexi, 

 regulariter crescentes, ultimus ad peripheriam subangu- 

 latus, antice breviter deflexus, bast planatus. Apertura 

 subangulato-ovata, sat lunata, peristomate simplici dis- 

 tincte labiato. 



Diam. maj. g ; ntin. 8. Alt 3 mill. 



Shell depressed and conical, umbilicus deep and 

 narrow not enlarging towards the base, fine and regular 

 striations, white with a dark chestnut-colored band at 

 the periphery running along the suture to the apex 

 and with a lighter one at the base. The 5 — 6 whorls
