H. A. Pilshry — Air-hreathing MoUusks of the Bermudas. 495 



Eulota similaris (Fer.). 



First reported by Hon. T. H. Aldrich, in 1889 (Nautilus III, 9) 

 and found in some abundance by Mr. T. H. Montgomery some years 

 later. The specimens collected by Prof. Verrill's party' are remark- 

 able for their great solidity, elevated spire and distant faint spiral 

 lines. The genitalia, however, are typical for the species. The 

 kidney is very long and band-like, as in Polygyra, being double 

 the length of the pericardium, and over half that of the lung. 



This species has been widely distributed by commerce from an 

 oriental center, and has long been known from Barbadoes, Rio de 

 Janeiro, Havana, etc. 



Valloma pulchella (Miill.). 



Recorded by Jones, 1876, and in Bland's list of 1881. The specific 

 identity of Bermudian specimens has been confirmed by Dr. V. 

 Sterki, from examples in U. S. Nat. Mus. (Proc. A. N. S., Phila., 

 1893, p. 278). 



Thysanophora vortex (Pfr.). 



Plate LXII, Figures la, \h. 



An abundant Bermudian species, taken by many, if not all, col- 

 lectors. 



Common under stones on the larger islands. A few dead shells 

 were found on Bailey Bay Island (Cook). 



^ This party consisted of Professor A. B. Verrill, Tale University, with M. C. Cook, 

 W. E. Porter, and C. S. Verrill, students in the Sheffield Scientific School of Yale Uni- 

 versity. They were in Bermuda during April and May, 1898. Much more attention 

 was paid by this party to the study of marine zoolopjy than to terrestrial forms. 

 Mr. Cook, however, devoted considerable time specially to the land snails, and to his 

 devotion to this part of the work the relative completeness of the collection is 

 mostly due. It was not practicable, however, to visit all parts of the islands, nor to 

 spend much time in searching for rare and minute species. Doubtless a thorough 

 search, especially in the swampy districts, would reveal a number of additional 

 species. Some of the rarer forms, especially of slugs, were obtained by collecting in 

 the night, with a lantern, when large numbers of snails and slugs could be found 

 creeping on the stone fences, which are all built of limestone and often whitewashed. 

 The owners of the fences sometimes complain that the snails eat the mortar from 

 between the stones and thus damage the walls. Several species occur in vast num- 

 bers, and some of them, especially Rumina decollata, are quite injurious to garden 

 vegetables and to fruit. — (A. E. V.)
