AUSTRALASIAN ANTARCTIC EXPEDITION. 
A figure of the capilliform chsetse is given by Gravier; but his interpretation of 
the hook is not quite in agreement with what I see. The large fang is surmounted by 
four others of much smaller size; and there are some laterally situated small teeth at 
the base of the large fang. Further, the bay between the fang and the bundle of threads 
is deeper and roughly semicircular in outline. 
It may be that these small differences depend on the segment or region of the 
worm from which the uncinus is taken.

Twenty specimens, carefully preserved in formaline, were collected by Mr. 
Hamilton at Macquarie Island, where they are common, embedded in sand and broken 
shells, between rocks, two inches below the surface at low tide. 
They vary in length from 40-140 mm. The colour in life is stated to be for most 
of them “ pale green with red gills.” These have, turned brown in the preservative; 
others were “ dark green ” in life, and have become almost black.

Garden Bay, Macquarie Island.

Fauvel); North Tasmania, Table Bay, S. Africa (Ashworth); Campbell

Of the three specimens in the collection, the largest measures 93 mm. in length; 
ts greatest breadth is 18 mm., its height 10 mm. It is thus larger than that described 
by Ehlers,
