186 Messrs. J. Wood-Mason and A. Alcock on 



names. Eumeles is especially remarkable, and we would 

 invite the attention of conchologists who hunt slugs (in old 

 collections of museums and elsewhere) to the unusual arrange- 

 ment of the tentacles in this genus, and to the fact that a 

 number of Eafinesque's species are still at large. 



The genus Meghimatium, v. Hasselt, 1824, was founded on 

 a species of this genus from Java, and was quite recognizably 

 described. The names Tebennophorus, Binn., and Incilaria^ 

 Benson, were both proposed in 1842, the probable priority 

 being in favour of the first. 



Morse in 1864 established the genus Pallifera for a species 

 with ribbed jaw. 



This review shows that several names for the genus, more 

 or less certainly applying to it, were proposed anterior to 

 1842, the date of Tebennophorus. Of these names Philo- 

 mycus and Meghimatium are the only ones available, Eumeles 

 and Limacella being clearly inapplicable. Since continental 

 authors generally have adopted the name Philomycus, it seems 

 advisable to retain that designation for the genus if Tebenno- 

 phorus must be rejected.
