46 Habits of Testacellus Scutulum, 



T. Scutulum, as Mr. Blair remarks above, is of a dirty 

 yellow hue, and T. Maugez differs from it in having its back 

 of a dark brown colour, and in the more cylindrical form of its 

 shell. The French naturalists, Mr. Sowerby remarked, sup- 

 pose the English T. Scutulum, with which they possess almost 

 no practical acquaintance, to be identical with the T. halioti- 

 deus of Faune Biguet, and described in Ferussac's Histoire, 

 and to which, indeed, it is most closely allied, but differs in the 

 form of its shell. T. Scutulum is figured in Sowerby's Genera 

 of Shells, T. Maugez' in Sowerby's Genera of Shells, and in 

 Ferussac's Histoire, pi. 8. fig. 10. 12. ; and T. haliotideus is 

 figured in Ferussac's Histoire, pi. 8. fig. 5 — 9., and two views 

 of its shell are given in Sowerby's Genera of Shells. — J. D. 



\Amax Sowgrbyi of Ferussac. — In Vol. V. p. 694. it is con- 

 jectured that Ferussac's " plate viii. D.," which he cites for a 

 figure of this species, had not been published up to the date 

 of offering the conjecture. The fact is otherwise : Mr. J. D. C. 

 Sowerby has since informed me that Ferussac's "plate viii. D? J 

 is published. 



Food. — JLlmax Sowerby? feeds on cabbage leaves when no 

 other food is obtainable. On Nov. 20th I shut up twenty or 

 more living specimens, and with them portions of cabbage 

 leaves plucked fresh off the plants, in a box, where they 

 remained confined until Nov. 26. On opening the box then, 

 the cabbage leaves had been much eaten, and although the 

 remains of them were then yellow, putrescent, and fetid, some 

 of the slugs were feeding upon them. I have subsequently 

 learned from Mr. Blair, in a note dated Dec. 2. 1832, that 

 " at this season L. Sowerby/ is very destructive to the celery 

 under ground ; and," Mr. Blair adds, " in taking up, lately, 

 my bulbs of Tigridia Pavbnia, I found many of them destroyed 

 by it." 



Eggs. — On August 31. 1832, I found an egg or two of this 

 species, as I then fully believed ; but, fearing the possibility of 

 error, I did not mention the fact in the notice, Vol. V. p. 693 — 

 697. On Nov. 29. I found a cluster of about a dozen of pre- 

 cisely similar eggs attached to the head of a living L. Sowerby? 

 which had buried its head in the soil, in its act of depositing 

 its eggs beneath the surface. I may here remark that other 

 individuals, on the same plot of ground, seemed to have crept 

 into the hollows and crannies of the soil, as if in shelter from 

 the approaching cold weather. I brought away some of the 

 eggs, and shall here attempt to describe one, as a sample of 

 the rest. The egg, in figure, inclines to oval, is soft, elastic, 

 nearly two tenths of an inch long, more than half its length 

 in breadth, as transparent as ground glass, but of a yellowish
