Mr. T. D. A. Cockerell’s Notes on Slugs. 
with Fdrussac’s figure. This slug is cylindrical, curved, and 
narrow (in alcohol) ; sole narrow ; ground-colour and colour 
of sole pale yellow, back thickly marbled with brown-grey, 
and with two longitudinal series of dark egg-shaped spots. 
Jaw bright-coloured, not ribbed. (Description from Brit. 
Mus. specimens.) 
Dr. Gray (Brit. Mus. Cat.) also describes L. carolinensis . 
Limacella nebulosa . 
P Eumelus nebulosus, Raf. Ann. of Nat. 1820. 
Tebennophorus carolinensis , Binney, Terr. Moll. U. S. vol. ii. p. 20. 
This and the last have hitherto been included together 
under the one name carolinensis , and it is not without mis- 
givings that I venture to separate them here *. Yet, from the 
specimens which I have examined, there would certainly 
seem to be a specific distinction between the northern and 
southern forms referred to carolinensis in the Eastern United 
States and Canada. The British Museum contains specimens 
of nebulosa as follows : — 
(1) From Mr. W. G. Binney, labelled T. carolinensis. — 
Ochreous, marbled with black above, the marblings 
rather inclined to be in three longitudinal series. 
Sole unicolorous. 
(2) W. Canada ( Dr . Maclagan). — Pale yellow, marbled 
above with brownish grey, the markings being a 
broadish dorsal and narrower lateral brownish-grey 
bands, with irregular spots over the rest, except sides 
near foot. Sole unicolorous. 
(3) Amhurstburgh, Canada West [Dr. 0 . W. Maclagan). 
— Like the last, but mottling grey and more diffuse ; 
two narrow dorsal and narrowish lateral bands, rather 
obscurely indicated in grey. Grey mottling thicker. 
Ground-colour pale yellowish. 
Comparing carolinensis with nebulosa , we note : — 
(a) The Virginia carolinensis . — Sole narrow, yellowish, 
pale, without transverse striae ; body smoothish . 
(b) nebulosa , no. 1 above. — Sole broad, brown, with strong 
transverse striae ; body rugose. 
* Mr. W. G. Binney writes (in litt. Sept. 9, 1890) : — u I am rather 
sceptical about there being two species .... as you say . . . . — there is 
a big species of Tebennophorus confounded with carolinensis , but having a 
ribbed jaw.”
