still other slight differences. According to Stanley Kemp (in: Fisheries, Ireland, Sci. Invest., 

 1908, I [1910], p. 124) in Proc. cafia/iculaia the rostrum falls slightly short of, or extends a 

 little beyond the eye; in P7'oc. aus/raliensis, however, it does not reach to half the length of 

 the ophthalmopods (B.vker) or reaches, like in the "Siboga" specimens, to the middle of the 

 eyepedimcles or even to the middle of the cornea, but extends never beyond the eye. The 

 antennal spine is well-developed in Proc. canalictilata and the ])leura of the 5'1' somite are armed 

 with 2 or 3 small acute teeth, in Proc. anstraliensis only with one, though the development 

 of 2 or 3 teeth may be owing to the much larger size of the specimens from Naples. The 

 measurements of the telson and of the three posterior legs of a female, long 34 mm., of Proc. 

 canalmilata from the Gulf of Naples accord, as regards their relative proportions, with those 

 of Baker's species (See the Table of Measurements). I, finally, wish to add that the rostrum 

 of Proc. canalicnlata closely resembles in a lateral view that of Proc. ausiralicnsis, with two 

 sharp teeth at the apex, of which the lower is twice as long as the upper and with a few 

 setae between both; in three of the Naples specimens the rostrum shows these characters, but 

 in the fourth, the largest of all, 40 mm. long, it terminat(?s in a single acute point. 

 Proc. aeguiiiuxna (Paulson) from the Red Sea is likewise a related form.
