694 On Birds observed in the Vicinity of Wei Hai Wei. 
on the birds of Chefoo (‘ Ibis/ 1874, p.424). Swinhoe’s 
informants were, however, very late in the season in exploring 
this islet, and almost all the nests at the time of their visit 
contained young birds ; they stated that no nest held more 
than two eggs or young. 
On May 15th thirteen fresh eggs of this species were 
obtained on Alceste Island, and on July 20th a couple 
more were taken. The nests were all placed in a small 
cliff which faces the mainland of North-East Promontory ; 
there were no nests on the grassy top of the island nor on 
any of the surrounding islets. The nests were not very 
bulky, the bases being of dried seaweed and coarse herbage 
and the linings of fine grass. Some nests contained two 
eggs and others three. 
In colour these specimens varied from a light brownish- 
green to a dark brown stone-colour, and the markings were 
of dark brown, grey, and slate. 
Fifteen eggs average 2*59 x 1*55 inches ; the length 
varied from 2*55 to 2*30 and the breadth from 1*61 to 
1*77 inch. 
Larus veg,e. 
These Herring-Gulls were first seen on August 14th, and 
by the end of that month a few were about Wei Hai 
Wei Harbour. By the middle of September they were 
abundant, and at the end of the month very numerous. 
The majority were immature, but a considerable minority 
were still in adult plumage. It is of interest to observe 
that Larus cachinnans was not met with at Wei Hai Wei, 
but it is the only Herring-Gull which occurs in full 
plumage at Hongkong, where adults of Larus vegce are 
never seen. Swinhoe met with this species at Chefoo as 
early as July. 
Larus glaucus. 
Glaucous Gulls were met with on several occasions at 
Shi Tao and about North-East Promontory in September 
and October, and usually in stormy weather.
