We have received from W. G. Torr, LL.D., of Adelaide, an in- 

 terestiiifr form of Chiton, which has been obtained on the coast 

 of Queensland, and have placed it, provisionally, in the genus 

 Enoplochiton of Pilsbry's Chitonidae,^ as that appears to be the 

 best fitted for its reception. 



Only one species has been hitherto described, Enoplochiton 

 niger, Barnes, which occui'S on the coast of Peru. It is very in- 

 teresting to find that -vve have a representative of this rare genus 

 in Australian waters. 



The following is the original description of the genus: — • 



Enoplochiton, Gray.

 outside and within ; the lateral areas and head-valve irregularly 

 studded with extremely luinute eyes. Interior minutely hniii- 

 nated and punctate in a peculiar pattern ; sinus deep, denticu- 

 late. Insertion plate of anterior and median valves slit into 

 teeth and sharply pectinated outside. Tail valve having the
