This .species has been for many years considered as simply a 

 .synonym or variety of Heterodontus Phillipjyi, and as such it has 

 been recorded in Gunther's Catalogue of Fishes. We, however, 

 in our first paper on the " Plagiostomata of the Pacific," gave it as 

 our opinion (1) that the Indian and Japanese Cestracions would 

 prove on examination to be a distinct or possibly two distinct 

 species. Some years after that paper was written we published 

 Part II. of the *' Plagiostomata of the Pacific," (2) in which we 

 gave a detailed description and figure of a Heterodontus, which the 

 Australian Museum had received from Japan. 



We recognised that specimen as the fish figured under the name 

 of Cestracion Fhillipjn in Perry's United States Expedition to 

 Japan, and we thought it not unlikely that it might be the C. 

 zebra of Grey. In the absence, however, of any proof of its 

 identity with that species, and finding it to be undoubtedly 

 distinct from Fhillippi, we gave it the name of Ja2wnicus. 



We have now to record the existence of another species of 

 Heterodontus which is undoubtedly the C. zebra of Grey. It is an 

 inhabitant of the China Sea ; was captured at Swatow, and was
