382 Mr. T. D. A. Cockerell's Notes on Slugs. 



with F^russac'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 nehulosa. 



? Euinelus nebuloms, 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 nehulosa 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 i^ehulosa, we note : — 



(a) The Virginia carolinensis. — Sole narrow, yellowish, 

 pale, without transverse strige ; body smoothish. 



{h) nehulosa^ no. 1 above. — Sole broad, brown, with strong 

 transverse stride ; body rugose. 



* Mr. W. G. Binney writes {in litt. Sept. 9, 1890) :— " I am rather 

 sceptical about there beiug two species .... as you say . . . . — there is 

 a big species of Tehennophorus confounded with carolinpnsifi, but having a 

 ribbed jaw."
