It appears to me very doubtful whether this can be considered a 

 species distinct from S. leptura. It is more probably a LrgfvarTety 

 of that species with more distinct white lines along the back, for 

 even in typical examples of S. leptura two faint white lines can be 

 o^asionally traced. I am, however, unable to settle this question 

 owing to insufficiency of material to work upon, and therefore prefer 

 tor the present to recognise two species in accordance with the 

 views of other zoologists, and especially in deference to those of Prof 

 i-eters, who has worked out this group with great care.

Head and muzzle as in S. leptura, except that the nose is not so 

 prominent above the face, although the extremity of the muzzle pro- 

 jects to a greater extent beyond the lower lip. Ears as long as the 

 head, much broader than in S. leptura ; the inner margin of the ear- 

 conch arises abruptly from the face above the anterior angle of the 

 eye, from which it is separated by a prominent wart, straight or 

 slightly concave in its lower third, then convex, succeeded by a 

 slight concavity, becoming again convex towards the tip, which is 

 rounded off ; outer margin straight or slightly convex from the tip 

 to a point opposite the base of the inner margin of the tragus, where 

 a well-marked emargination occurs, then forming a large slightly 

 convex lobe, which terminates abruptly midway between the base 

 of the tragus and the angle of the mouth, but on a lower level : tragus
