obviously the “ Limax succini colore, albidis maculis insignitus,” of Lister, 
Conch, t. 101. 6., but as the letter A is not placed at the figure, Avhich is the 
usual mark of an English species, there is no evidence of its being native. 
Gen. XV. TESTACELLA. — Vent and pulmonary cavity 
nearly terminal. Foot extending on each side beyond the 
body. 
50. T. Maugii. — Reddish, with scattered brown spots, and 
a stripe of brown on each side. 
Fer. Hist. Moll, i. 94. t. viii. f. 10-12. Miller^ Annals of Phil. xix. 380. 
— In nursery grounds, Bristol. 
Tentacula filiform ; mouth orange. Shell ovate, lengthened, convex, co. 
vered with a dusky cuticle, striated by the layers of growth ; rounded and 
effuse anteally, ending retrally in a short spine, with a slightly prominent 
knob ; margin of the opening entire, subquadrangular. — This species was ob- 
served by Mr T. Drummond (at present engaged in exploring the Arctic 
Botany of North America) in 1812, in the nursery grounds of Messrs Sweet 
and Miller. Specimens were transmitted by Dr Leach to Baron Ferussac. 
It feeds on the earth worm, into the holes of which it effects its entrance. 
Eggs few, ovate. It inhabits Teneriffe, and was probably introduced along 
with exotic plants. 
51. T. haliotoidea. — Greyish clouded, or reddish, without 
spots.

Moll. i. 94. t. viii. f. 5-9. — T. scutata. Sower. Gen. Ric. Shells, 1, 3, 6. 
— In a garden at Lambeth. 
Tentacula cylindrical ; a groove on each side, from the head to the shell. 
Shell ovate, depressed, rounded anteally, thick, brown, striated by the layers 
of growth : acuminated retrally, with an imperfect spire, in the form of a 
minute light coloured knob. — This species was found in Mr Sowerby’s gar- 
den at Lambeth. The specimens obligingly presented to me by Mr J. C. 
Sowerby, incline me to consider them as identical with the species long ago de- 
scribed by Draparnaud. In the description Mr G. B. Sowerby adds, “ the 
animal of this species bears a near resemblance to that of T. haliotoidea.^ not 
having the double row of tubercles running from the head to the anterior 
part of the shell so conspicuous in T. Maugii."

Gen. XVI. CYCLOSTOMA. — Peristome of the shell thick- 
ened, entire. Tentacula hnear, subretractile, the second 
pair minute, bearing the eyes.

dinally striated.
