be reflected on the part behind the bend, when resistance is opposed 

 to it during erection. Further, a large dilatation, or lacuna magna 

 of the urethra is seen. From these circumstances it appears 

 evident that the seminal fluid must lodge in this lacuna, and be 

 wiped out into the female passages in the process of withdrawal. 



In the White-beaked Dolphin it was further shewn that there 

 are four openings in the floor of the first part of the urethra, 

 namely, to the sides, the two vasa deferentia, and between them 

 two larger openings leading into one sinus pocularis. The exhibitor 

 commented on this as a condition which he had never before met 

 with, and remarkable as representing double vagina in the female. 

 Each testis is attached to the corresponding pelvic bone by 'a 

 gubernaculum, and connected with it is a large rete mirabile, and 

 the small arteries composing this come off in numbers from the aorta.

 Spruce, a new species of Moss which had been sent to him by Mr. 

 G. Stabler, for exhibition to the Society. This moss, which is

A finely-mounted collection of Fungi, chiefly Agarics, from 

 Germany, were sent for exhibition by Mr. J. C. Christie. The 

 specimens were all carefully prepared to shew the most important 

 features in the structure of this interesting botanical group. 



Mr. John Kirsop, F. S.A.Scot., V.P., exhibited two small speci- 

 mens of the Horned Trunk Fish, Ostracion cornutus, I in., from 

 the South Atlantic, and stated that these little fishes belonged to a 

 genus of the Sclerodermi, which had the body entirely encased in a 

 carapace or bony crust, leaving only the tail, fins, and mouth capable 

 of movement. They are nearly all natives of the Ind' in and 

 American seas, none being found in British waters. Some of the
