According to Pocy's statement, this species makes a remarkable 

 exception to most of the Serrani in having at least twelve stems of 

 the pyloric appendages, each divided again into several branches ; 

 an increased number is also to be observed in S. inermis, from the 

 same locahty. The description of S. octocinctus, given in the Faun. 

 Japon. p. 7, pi. 4«, agrees exactly with the specimen mentioned 

 above. There is another specimen in the Collection of the British 

 Museum, said to be from the Isle de France, which cannot be separated
