REPORT — 1856. 



60. The following species and localities are extracted from the " Concho- 

 logical Illustrations, by G. B. Sowerby," a small but exceedingly valuable 

 work, remarkable for the excellence of the figures, but the disappointing 

 brevity of its information.

54 Bulinus unifasciatus = Bulinulus undulatus. Guild. St. Vincent's.

61 . The following are taken from the " Thes^aurus Conchyliorum," by 

 G. B. Sowerby, continued by G. B. Sowerby, Jun. The illustrations are 

 excellent ; but some of the later numbers do not equal the earlier portions. 

 Several of the Monographs are very carefully drawn out by Messrs. Hanley, 

 Hinds, and A. Adams. There are the same geographical errors as in other 

 similar works.

t This shell, described as " differing from the typical genus in the canal of the aperture 

 being almost obsolete," is regarded by several eminent conchologists as a dead Melania. It 

 was found near the mouth of a river.
