 Distribution. This species is extremely widely distributed 

 throughout the circumtropical zone ; it is recorded from the East 

 American region, Mediterranean subregion (Dalmatia &c.), and 

 the greater part of the Indo-Pacific region. 



Several specimens fro]n Eotuma from 29 mm. x 11 mm. to 

 106 mm. X 23 mm. 



The colour is characteristic, the dorsal violet-brown blotches, as a 

 rule, coalescing to form transverse bands ; but in one specimen the 

 blotches are quite distinct, forming two longitudinal rows, as in 

 the two specimens described by Ludwig from Tahiti and Surinam 

 respectively. 



The deposits are typical and I have no opportunity of confirming 

 Ostergren's Yiew that H. cqjhanes Lampert is the young form of 

 ff. imjiatiens Forskal. 



In four specimens dissected the arrangement shown in the 

 following table occurred : —
