636 NOTES FROM THE SOUTH. 
early on April 22nd I observed a great assemblage of the 
latter species resting on a rock at the entrance into the 
harbour of Sebenico. 
Larus MARINUS. Great Black-backed Gull. 
From the 14th to the 18th of April I often observed one 
or two between Ragusa and Lacroma. 
LARUS MICHAHELLESI. Yellow-legged Herring-Gull. 
From the 6th of March to the 26th of April I everywhere 
saw great numbers of this Mediterranean form of the Herring- 
Gull in the Istrian and Dalmatian waters. On the rivers in 
the north of the latter country it wanders many miles up into 
the mountains. 
Larus Fruscus. Lesser Black-backed Gull. 
Everywhere to be met with in the same district as the 
preceding species, but not so abundantly, nor did I ever know 
it to leave the open sea and the harbours to fly into the 
interior of the country. 
Larus rRipipunDus. Black-headed Gull. 
In the Dalmatian waters I everywhere saw great numbers 
in March and April. 
PUFFINUS ANGLORUM. Manx Shearwater. 
First observed at the entrance to the Mar di Novigrad on 
April 24th. 
PHALACROCORAX CARBO. Common Cormorant. 
On March 12th a single bird was seen on the coast at 
Lacroma. On April 23rd I observed several near the little 
islands between Zara and Nona.
