CURRENT LITERATURE. 65 



Dr. Dall then proceeds to discuss the surface characters — especially of the 

 Bnliviitli — and concludes tliat the peculiar crenulation or wrinkling of the sur- 

 face which "is correlated with aridity or alkalinity of environment, maybe 

 regarded as having been impressed upon species which first gained a foothold 

 in the arid region, and as having persisted to some extent in their descendants 

 when the latter succeeded in reaching the upper and more congenial zones of 

 the islands." 



' Further, he compares the fauna of the Galapagos Islands with that of 

 other oceanic and isolated localities, and incidentally raises a question which, 

 unfortunately, he does not proceed to solve : namely, why the species of 

 En:L'donta with basal lamellae are confined to oceanic islands ? Finally, a 

 valuable summary of the fauna both systematic and anatomical is given ; the 

 following is described as new : BuUmulus nesioticus ; and figures are given of 

 other species. We have to congratulate Dr. Dall on the publication of what 

 will be the standard work on these islands.
