in the species. The sixth abdominal somite, which was wanting in 
the previously described specimen, is grooved in all the specimens 
and is wrinkled on either side as in typical L. maculata. If Kemp’s 
variety had been founded on the form of the rostrum only these 
specimens would have had to be attributed to it, but since five out 
of seven possess the norma] numbtr of spints on the dactylus. and 
the sixth abdominal somite is typical in form, it seems better to 
regard them as a well-marked race of the typical species. 
In addition, the collection contained a single specimen from 
Broome of another species, which appears to be locally called 
“Zeppelin” and to occur in deep water. 
It agrees in every respect with Odontodactylus japonicus, 
de Haan, which has previously been recorded only from the seas of 
Japan and China and from 55 fathoms off the Seychelles. The 
genus Odontodactylus had not previously been recorded from Aus- 
tralia. 
In conclusion I may mention that in October last I collected a 
male specimen of Gonodactylus chiragra , Fabr,, in a small rock pool 
on the reef at Port Hedland.
