2o8 COCKERELL AND COLLINGE : CHECK-LIST OF SLUGS. 



subfasciate form, supposed to be the young of the yellow 

 variety. Mr. Gain (Sa. 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 about 

 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 subreticulatus 

 and elincolatus, 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 in. bocagei. Dr. Scharff figures a sub-variety of this, which he 

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

 British representatives of bocagei. I think our forms should 

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

 the name bocagei simply may give rise to misunderstandings. 

 (See sul cat us.) 



367 0. faciatus, Seib. This is older than the faciaius, 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/. mulleri. This is Miiller's variety, " ater, carina dorsi pallidc 

 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 uiiillcri-Wka 

 form of sulcatus. 



367 r. violesceiis. This may well be the same as hiberiuis, 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, supposed by some to be a form 

 of A. ritfi/s.
