196 On a new Lizard Jrom I'ltt hhuul. 



As to tlie relative positions of the two organs in tlie 

 various exani])les, it lias already been mentioned tliat in the 

 ppeelnien under C(.)nsideration the female section occu})ied the 

 anterior position, whilst the smaller male organ was confined 

 to the ])osterior portion of the abdominal cavity; but in that 

 described by Dr. A. J. Smith (which measured only 3^ inches 

 in length, and was therefore evidently not matured) the 

 reverse was the case : — "The uj)per [anterior?], lai'ger, and 

 bulkier portion, 2 inches in length, was a distinct testis or 

 milt; the lower [posterior?] and more tapering half was roe 

 and 1^ inches in length, the separation between the two 

 quite distinct and divided vertically." Only one side of the 

 generative organs was preserved, but Dr. JSmith says that the 

 other side was of exactly the same character. In Mr. Yarrell's 

 specimen the disjjosal of the parts differed from both these : 

 the " lobe of the teniale, or hard roe, was on one side, and tlie 

 lobe of the male, or soft roe, on the other." 



I'liat the occurrence of such compound sexual organs in the 

 lierring is of very rare occurrence (it is more frequent in 

 members of the cod family) seems probable, for 1 cannot 

 learn of like examples having been previously observed by 

 the Yarmouth fish-curers, through whose hands many millions 

 of these fish pass annually, and who are very ready to mark 

 any departure from the normal.
