NOTES. 



I c. It is a matter of opinion whether maciilaius (Leach) or 

 krynickii should take priority. 



I e. The form ?naailatus, Pic., is hardly distinct from punctatus, 

 Esm. ; of course, Picard's name has priority, but it is not 

 the same as maculatus, Leach. 



I /. Moquin-Tandon is the author of this variety, strictly speaking. 



\ q. \ have seen the type of inegaspidus in the British Museum. 

 The external mouth-parts are those of maximus, not of 

 flavus ; so also the reticulation, &c. 



I r. strobeli, as I have identified it, is only a pale or semialbine 

 form of maxinms. 



I ^. sjibunicolor, Simroth I have seen no description of this. 



2-8. Subspecies or races not studied by me, and of quite minor 

 rank. 

 9. cinereo-7iiger. After all the discussion that has taken place, 

 I feel somewhat diffident about adding more. For my 

 own part, I have never been at a loss to identify cinereo- 

 niger by external marks, even when the sole has been 

 unicolorous. Yet it is only fair to state that an example 

 from Wales, which I was strongly persuaded was cinereo- 

 niger, though the sole was not banded, was at Leeds 

 referred to maximus.^ Probably the specimens are still 

 preserved there, and if it is really maxi/nus, I must retract 

 the above statement about the identification of cinereo-tiiger. 

 This slug was recorded by Mr. Fenn as cinereo-fiiger var. in 

 Journ. of Conch., 1887, p. 198 (see also p. 137). In the 

 British Museum there is a large cinereo-niger, entirely 

 white (var. a/bus, Paasch.).'^ 



*In all probability this was cinereo-niger. — W. E. C. 



'It would be interesting to know in what manner the var. alius, \\\\ Stein, of/-, maxiinus, 

 L., differs from this var. alius of Paasch. — W.E.C.
