12 San Juan Fernandez; coll. Prof. E. C. Stearns [as " L. penitaria, 

 Wood"]. 



Neither in Reeve, Philippi, nor in the Index Test.! 



31. Littorina irrorata. 



Turbo irroratus, Say, Journ. Philad. V, 1822, June, p. 239 ;=Phasianella 

 sulcata, Lamarck, 1822, August, p. 54 ; sect. Littorinopsis. 



16 Florida and Hog Island [Virginia]; coll. Rev. E. R. Beadle, Prof.

32. Littorina mauritiana. 



Phasianella mauritiana, Lamarck, Hist., 1822, Mauritius ;=L. Icevis, 

 Phil, [not of Reeve'], P. Zool. 8. 1845, Sab. ? ; fide v. Martens, from 

 Hongkong and Pt. Jackson ; sect. Melaraphe. 



6 Mauritius ; coll. G. Nevill and J. Caldwell, Esqrs. 



Very closely allied to L. obesa, but smoother and of different 

 coloration. They may be only varietal forms ? These speci- 

 mens are most admirably and exactly represented by Philippi, 

 III, PL VI, fig. 6, as L. Icevis, Locality ? The L. Icevis 'of 

 Reeve, I need scarcely say, is a totally different Australian form. 

 Prof. v. Martens would rather consider L. Icevis, Phil., as a form 

 of L. gldbrata.

Scarcely specifically separable from L. mauritiana, as already 

 pointed out by Philippi [under L. Icevis']. Krauss records it
