36 PHOLAS. 



this species, and from the words ' hinc reticulato-striata/ 

 without any mention of the prickles, his description was most 

 probably taken from the former ; but the habitat ' inter 

 Europaj scopulos,' gives the latter an equally fair claim to be 

 arranged as the Linnasan P. daetylus. — Dr. Solander, and 

 Dr. Pulteney were, however, of a contrary opinion, and they 

 distinguished the present species by the name of P. Mans.
