colour, is longitudinally ribbed, and bears at each corner 
a long filiform process, the function of which is to twine 
round seaweeds, etc., and so anchor the egg. The chilo- 
scyllian egg-case, on the other hand, is of a shining purplish- 
black and perfectly smooth; it is also shorter and broader, 
and lacks the sub-anterior restriction of the typical scyli- 
orhinids, being oval. The embryo, which is curled round the 
yolk-sac, lies nearest to the posterior extremity of the case, 
there being between it and the anterior end a closely 
appressed space. But the most remarkable difference 
between the two forms is in the means of attachment, for 
in place of the tendriliform processes of scyliorhinid egg- 
cases, that of C. punctatum has a loop formed of two fibrous 
extensions, placed on the dorsal edge, at some distance from 
either end. From a case received from Mr. Jameson it 
seems certain that the loop is woven round the stem of the 
support selected as the nursery, by the lips of the parent 
after deposition of the egg. This specimen was fastened 
to the stem of a colony of worm-tubes which is so thickened 
and branched on either side of the point of attachment that 
it could not possibly have been slipped on either from above 
or below. Most of the cases examined were collected by 
Mr. J. T. Jameson at Woody Point, Moreton Bay, but we 
have also seen some from Dunk Island, where they were 
taken by Mr. E. J. Banfield, Cat. Nos. 420 and 906. Their 
average measurements are 97 X 52 mm.
