LOTA MOLVA. 411 



The kidneys are in the usual situation, viz. along the back. The two 

 ureters enter the bladder about half an inch from the neck upon its left 

 side. The bladder is pretty large and oblong, lying on the right side 

 of the rectum and ovibags : it is pyramidal, as in the ox : the urethra 

 is an inch long, and opens close to the anus. 



Two very long bodies He on the back on each side of the rectum or 

 behind it, which I suppose to be testicles, but where they enter I do 

 not know ; nor did I see anything like a penis. 



The ovaria are two pyramidal bags lying behind the rectum ; they 

 communicate before they open externally; their internal surface is 

 laminated with pretty broad laminae, which surfaces are studded very 

 thickly with a vast number of ova, as if granulated. The common 

 opening is close to and behind the anus 1 . In what manner this fish 

 spawns I have not been able to determine. 



Upon the sulcus made by these two bags, lies another bag, but not 

 so large, which opens by a small orifice close to the verge of the anus : 

 it was filled with a white matter. This bag I suspect to be the bladder 

 of urine. 



As a wolf-fish has no sound [air-bladder] : quaere, what is its specific 

 gravity ? The wolf-fish has the skin of the body continued over the 

 eye ; but at the cornea it is transparent ; here the skin is joined to the 

 cornea by a loose transparent cellular membrane 2 . The ear is oblong 

 in the direction of the head of the fish. The valves of the bran- 

 chial artery are at the beginning, not at the termination, as in some 

 fishes 3 . 



There is no lateral nerve. There is no duct running along the body, 

 but a good many about the head; a row of which pass along the side 

 for some way, and communicate [with one another]. 



[Order Anacanthini.] 



The Ling [Lota rnolva, Cuv.]. 



The ling has a sound. The nostrils are as in the salmon. It has 

 the complete tunica conjunctiva, as in the cod, and has a fine eye for 

 showing the retina ; viz. the internal layer is strong, and the external 

 one pulpy. There are two choroid coats, an internal brown and an 

 external silver-coloured. It has a vast number of caeca at the pylorus, 

 filled with a white mucus.
