Typhlonarke is a new generic name proposed for Astrape aysoni 
Hamilton. The genus differs from Narke (Astrape), in addition to 
other peculiarities, by its only representative being blind. Arhyn- 
chobatis asperrimus is the type of a new genus and species of the 
Rajidee allied to Psammobatis. 
In addition to a detailed description, some interesting habits 
of Eptatretus cirrhatus are supplied, illustrated by photographs of the 
lingual teeth and their effect on the body of another individual of the 
same species. 
The egg-cases of Cephaloscyllium laticeps and Raja nasuta are 
figured, those of the former species being for the first time made 
known.
