DISCOVERY REPORTS 



Japan, under the name oi Paraceratias mitsiikiirii , and Regan has shown that apart from 

 the presence of the tentacle-like ray in front of the caruncles this is exactly similar to 

 Cryptosparas couesii. Another fish from Japan described by Giinther as Ceratias 

 carunculatus, which was 35 mm. in length, has this ray represented by a slight pro- 

 minence, under which is a gland with a pore, but likewise resembles Cryptosparas 

 couesii in other characters. It is of some interest to find a species with this ray on the 

 back occurring in both genera.

Family HIMANTOLOPHIDAE 



Genus Paroneirodes, Alcock, 1890 



Regan, who had not seen Alcock's specimen, united this genus with Diceratias, but 

 it may be distinguished by the smooth skin, feeble teeth, and more backward position 

 of the illicium, which arises between the sphenotics.
