the double row of tubercles running from the head to the anterior 

 part of the shell, so conspicuous in T. Maugei. 



Testa. — Ovata, antice paulura acuminata, extus plana, clavicula 

 arcuata elevata. (Loudon's Mag. Nat. Hist. vii. 229). 



The colour of this species, Mr. Lukis says, is generally of a sickly 

 yellow spotted with brownish specks, mixed with pale orange along 

 the lower parts. This species, Mr. Blair remarks, is of a dirty yellow 

 hue, and T. Maugei differs from it in having its back of a dark brown 

 colour, and in the more cylindrical form of its shell. 



Mr. Sowerby thinks that T. Scutulum is identical in species with 

 those sent by Mr. Lukis from Guernsey. (Loudon's Mag. Nat. Hist, 

 vii. 224). Mr. Lukis was acquainted with his species so early as 

 1801. 



French naturalists suppose (as remarked by Mr. Sowerby) the 

 English T. Scutulum, with which they possess almost no practical 

 acquaintance, to be identical with the T. haliotoideus of Faure Biguet 

 and described in Ferussac's e Histoire,' and to which indeed it is most 

 closely allied, but differs in the form of its shell. 



Habitat. — Discovered by Mr. Blair at Stamford Hill, London ; by 

 Mr. Sowerby in a garden in Kennington Road, Lambeth ; at Notting 

 Hill Terrace, London ; was not rare in the kitchen and forcing gar- 

 dens at Kensington, and in other places in the neighbourhood of 

 London ; and may, in the opinion of Mr. G. B. Sowerby, be consi- 

 dered as a native of this island. 



Habits, 8$c. — Mr. Blair, of Stamford Hill, near London (Loudon's 

 Mag. Nat. Hist. vi. 43), watched this slug for four years with consi- 

 derable interest. That gentleman observed that they were generally 

 to be found near the greenhouse, and were seldom seen more than 

 fifty yards from it. He described it to be of a dirty yellow colour, 

 and, when crawling on the surface of the ground, to be about three 

 inches in length, and furnished with a small rudimentary shell at the 

 tail end. 



Mr. Blair thus continues his observations: — "In winter it buries 

 itself from one to two feet deep in the earth, and appears on the sur- 

 face of the ground occasionally with other species; but from the time 

 of my first observing it until the present I have never seen it feeding 

 on any species of vegetable. One morning last spring, on passing a 

 narrow border, which had been previously watered with lime water, 

 for the purpose of destroying slugs, I observed several of the yellow 

 species amongst others dead, and close beside, or near the head of 

 several of them, lay a dead worm. The man who performed the
