220 ON MARINE WOOD-BORING ANIMALS. 



I leavn from Mr. Hamer, however, that this is merely cine to 

 a transposition of labels, the Ghelura, whose identity with the 

 European species is vouched for by Prof. Chilton, being abundant 

 and well known at Auckland. 



It appears doubtful whether there is any trustworthy record of 

 Chelura occurring apart from Limnoria. The gathering from 

 Simon's Town seemed at first sight to consist exclusively of 

 Chelura, but on closer examination 13 specimens of Limnoria 

 were discovered among more than 300 of the other genus. If 

 these numbers are at all representative of the proportion in 

 which the two species were living in the wood, the great pre- 

 ponderance of Ghelura is very remarkable. The only previous 

 record of Ghelura from South Africa appears to be that of 

 Hammersley-Heenan, who found it at Port Elizabeth in 1893 

 (Trans. S. African Phil. Soc. v. p. 316), and it is noteworthy that 

 no mention is made of its being accompanied there by Limnoria.
