GIZZARD IN FISHES

rather hard at its distal extremity ; in another 

 Clupeoid genus Dussumieria, the pylorus appears 

 as an arched muscular tube lying across the body 

 cavity from left to right, the concavity of the arch 

 being directed forwards (Fig. 9). 

 In a species of Grey Mullet 

 from Ceylon which I identified 

 as Mugil olivaceus Day, I found 

 the gastric ccecum rudimentary 

 and the cardiac division of the 

 stomach was followed by a round, 

 white, muscular, bulbous gizzard ; 

 the intestine was full of fine sand ; 

 six pyloric cceca embraced the 

 gizzard; another specimen had 

 only five pyloric cceca. What, 

 however, surprised me very 

 much at the time and I have 

 not found it mentioned in any 

 work which I have consulted 

 since was the discovery of an 

 almost precisely similar gizzard 

 in a Clupeoid fish, Chatoessus 

 nasus, which frequents the same g-c- Gastric [cardiac]

 In this species (C. nasus} the * Destine, 

 stomach is frankly destitute of a cardiac ccecum, 

 and terminates in a round, muscular, red, bulbous 

 gizzard. In one of the specimens dissected, the 

 gizzard and intestine were full of fine sand as in
