182 AMERICAN JOURNAL 



rest to the Section. A la,te paper by A. G. More, in the An- 

 nals and Magazine of Natural History, gives, ostensibly for the 

 iirst time, an account of the animal of Limncea involuta, Har- 

 vey. The desctif)tion of tliis j-pecies was 7'ead by Mr. Harvey 

 to the Linncan Society in Ajiril, 1834, but the description was 

 first published in the Annals of Nat. History, v, 1st series, p. 

 22, March, 1840, by AV. Tliompson, Esq., with a thorough 

 account of the form and anatomy of the animal by John Goodsir, 

 Esq. In view of this fact, it is extraordinary that thirty years 

 after, in the same periodical, the animal should be described 

 again, as for the first time."
