FAMILY COLIMACEA. 113 



This species, the smallest of our Pupa, but larger than auy Ver- 

 tigo, lias been well observed by Mr. Jeffreys, although it is not 

 entitled to the name by which he described it. The animal, he says, 

 is furnished with short tentacles of a lighter shade than the upper 

 part of the body, which is of a yellowish-grey or slate colour, with 

 several dark lines or streaks along the sides, and underneath it 

 is milk-white. " This is a shy little creature," adds Mr. Jeffreys, 

 " although tolerably active when inclined to make its appearance. 

 It has a singular habit of withdrawing slowly one of its eyes, which 

 rolls backwards like a little ball until it reaches the neck, while the 

 tentacle which supports it remains extended to its full length. This I 

 have observed being done when there was no obstacle in the way. 

 It also retracts occasionally and apparently without any reason, one 

 of its horns, and not the other." The shell is of an ovate cylindri- 

 cal form, with the aperture compressed into a characteristic trian- 

 gular shape, furnished with as many as five parietal teeth, two of 

 which are more internal than the rest, and have been observed by 

 Mr. Alder to pass thread-like round the columella. 



Pupa Anglica was discovered about forty years ago at Scarbo- 

 rough, by the now venerable Mr. Bean of that place, and named 

 by De Ferussac, who acknowledges having received specimens from 

 him. No formal diagnose of characters is given in the ' Tableau 

 Systematique ' with the name, but it is accompanied by remarks, 

 which leave no room for doubt on the species. After giving "En- 

 virons of Scarborough " as its habitat, M. De Ferussac says, " This 

 curious species may possibly be a Pupa ; it is as stout as a Pupa 

 (Coclilodonta) muscorum. It is consequently the largest Vertigo in 

 Europe, if it belongs to that genus." Specimens were also depo- 

 sited in the British Museum, and figured and named by Dr. Gray, 

 Pupa Anglica, in the Supplement to Wood's ' Index Testaceolo- 

 gicus.' 



The geographical range of the species has not been satisfactorily 

 established. It has been collected in the west of Scotland and 

 throughout Ireland, and in many scattered parts of England and 

 the Channel Isles. Morelet met with Pupa Anglica in the neigh- 

 bourhood of Cintra and Oporto, and the Abbe Dupuy gives Algeria 

 as a habitat. M. Moquin-Tandon includes the species in his mol- 

 luscan fauna of France, on the strength of having once found a 

 single specimen of the shell in the mud of the river near Toulouse.
