Fide v. Martens from Mauritius and =Z. serialis. I cannot 
but think, however, this must be merely a form of L. glabrata 
[my L. obesa, var. glabrata]. I have never seen Mascarene 
specimens that agree with those of the Sandwich Isl.; though 
indeed the two species are perhaps scarcely more than geo- 
graphical races? Three of the above agree with Reeve’s fig. 
of L. tenebrata, probably the female form. 
var. serialis.

Sandwich [slands, 
3 Sandwich Islands; ex c. Prof. W. Newcomb [as ZL. serialis], 
A rather distinct form, does not agree well with Souleyet’s 
figure.
