34 COCKERELL AND COLLINGK : CHECK-LIST OF SLUGS. 



subfasciate form, supposed to be the young of the yellow 

 variety. Mr. Gain (Sd. Goss., 1890, p. 45) remarks that 

 the young of light-coloured varieties of this species show 

 stripes a week or two after leaving the egg. 



367 k. scharffi. Back black, sides yellow. Dr. Scharff records this 

 from Ireland, and from what he states it appears to be 

 quite common at Raheny, near Dublin. Although I am 

 quite unable to understand Dr. Scharff's views al)out 

 classification, and believe he equally fails to understand 

 mine, or Dr. Simroth's (or did so when he last wrote on 

 the subject), I may perhaps venture to give this form his 

 name in recognition of the value of his work on Irish 

 slugs. It happens that the forms I named subreticul lius 

 and elineo/afiis, years ago, are but sub-varieties of this 

 scharffi, but inasmuch as their names express peculiarities 

 not necessarily inherent in the variety, I have disregarded 

 what might seem the strict requirements of priority. 



367 m. bocagci. Dr. Scharff figures a sub- variety of this, which he 

 found in Ireland ; and Mr. CoUinge has written on the 

 British representatives oibocagei. I think our forms should 

 be separated as one or two sub-varieties, as the citation of 

 the name ^^^^ra^i?/ simply may give rise to misunderstandings. 

 (See sulcatus.) 



367 0. faciafns, Seib. This is older than the faciatiis, Ckll., having 

 been published in Mai. Bl., 1873, p. 190. I have no note 

 of its peculiarities, and do not know whether it has any 

 standing. Pollonera, in his revision of the genus, does not 

 recognise it. 



367/. midUri. This is Miiller's variety, '■'■ ater, carina dorsi pallide 

 virente." The word '''' carina'' can hardly be supposed to 

 refer to any distinct keel, and so far as one may judge, the 

 slug must be very similar to Dr. Scharff's Irish form of 

 var. bocagei. Therefore, by strict priority, we should 

 perhaps place bocagei as a sub-variety of mulleri — or it 

 may be more correct to say that bocagei is the //////Ar/-like 

 form of sulcatus. 



367 r. vioiesctns. This may well be the same as Jiibcrnus, but as the 

 latter is claimed to be a distinct race or species, instead of 

 a colour-variety, I give it the benefit of the doubt. 



367 s. bicolor. This is not Moquin-Tandon's bicolor, but is based 

 on a little slug 30 mm. long, supi)ose(l by some to be a form 

 of A. rufus.
