Fide v. Martens from Mauritius and =L. 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. 



Littorina serialis, Souleyet, Voy. Bonite, 1852, pi. XXXI, figs. 34-86, 

 Sandwich Islands. 



3 Sandwicb Islands ; ex c. Prof. W. Newcomb [as L. serialis']. 



A rather distinct form, does not agree well with Souleyet's 

 figure.
