Dhappa near Calcutta (if the locality is correct) must have been taken in brackish 

 water. 



The series examined exhibit considerable variation as regards marking, but all 

 the specimens differ from Giinther's figure/ in that the markings on the posterior 

 part of the sides of the body take the form of streaks instead of spots. There is 

 considerable variation in the length of the tentacles and in the form and size of the 

 tuft at its extremity. Day's figure is taken from a shrivelled and distorted speci- 

 men stiU in the collection of the Indian Museum. The body is much deeper than 

 he represents it. 



Antennarius nummifer, Cuv. 



(Platei, fig. 5.) 



If Günther Ms correct as to the synonymy of this species, Day's figure in the 

 Fishes of India ^ represents not it but a variety of A. commersonii , Giinth. There is, 

 however, a specimen in the collection of the Indian Museum that agrees fairly well 

 with Bleeker's figure^ of A. coccineus, which Günther regards as a representation of 

 the true A . nummifer. It is by no means improbable that these three forms, as well 

 as several others,"" will ultimately prove to be conspecific. 



Antennarius commersonii (lyacép.). 



Day's specimen in the collection of the Indian Museum, although apparently 

 not the one he figured as A. nummifer in the Fishes of India , belongs perhaps to 

 Günther'syl. commersonii var. B. The spots, however, are less numerous than in 

 the individuals figured by the latter author. There are several young specimens in 

 the collection (length from 28 to 42 mm.) which agree fairly well with the definition 

 and figure of var. A of the same species, except that the first dorsal spine is dis- 

 tinctly shorter than the second. Perhaps they are the young of that form. These 

 specimens are from Bombay.
