 Loc. Lifu, Loyalty Islands. 



Two specimens, 5*6 cm. and 8T cm. in length. 



The larger specimen contained a Fierasfer 8 - 2 cm. long, which Mr Boulenger has 

 kindly identified for me as F. homei Richards. Rosette-shaped bodies as well as inter- 

 mediate forms between these and the much more abundant C-shaped deposits occurred 

 as figured by Ludwig; S-shaped deposits excessively rare.
