Observation. — Mr. T. Drummond, jun. while engaged at 

 Messrs. Sweet's and Miller's Nursery, informed me, in 1815, of 

 the occurrence of a limax in their grounds, with a minute shell 

 at its tail. This proved to be a testacella, and has been lately 

 described by Mr. G. B. Sowerby as a new species in his recent 

 publication on the Genera of Recent and Fossil Shells. It pro- 

 bably was introduced into that Nursery with foreign plants, but 

 propagates now freely in the open ground ; bears the winter, and 

 increases much in rich soil ; so that it can no longer be consi- 

 dered as an alien. I have sent from time to time a great many 

 specimens to my scientific friends ; so that I believe they are 

 now pretty much distributed, and in the collections of many 

 British conchologists. The animal lives on earth worms, which 

 it draws in, with its proboscis-like mouth, entire ; and if taken 

 hold of, when thus gorged, disgorges it immediately. The 

 earth worms frequently swallow the young testacella, and we 

 may sometimes meet the shells in their intestines. The testa- 

 cella lays but few eggs ; these are ovate, and if placed on the 

 hand, frequently burst hke a soap-bubble, dispersing in minute 

 fragments.
