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 Eagusa 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 FUSCUS. 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 RIDIBUNDUS. 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.
