L. — On the su^iposed Rediscovery of ^^ Moseleya " in 

 Torres Straits. By S. Pace, F.Z.S. &c. 



Among the collections obtained by the 'Challenger' Expe- 

 dition was included a single specimen of a coral for which 

 Qiielch * founded the genus Moseleya^ with the single species 

 M. hdistelhtta, Qiielch. 'J'his form, which until now has only 

 been known from the unique type specimen in the British 

 j\luscum, owes its great interest to the deductions which have 

 been drawn as to tlic supposed relationshij) of the genus to 

 the so-called livgosa of Pala;ozoic times, and as to the affinities 

 of the latter grouj). Thus, Quclch placed Moseleya in the 

 Cyatlioj'JiyUidtv ; and even in the most recent work on corals f
