634 NOTES FROM THE SOUTH. 
observed some at Fort Opus, and on April 9th there were 
many of them on the dunes in front of the lagoons at the 
mouth of the Narenta and on the marshes along the banks of 
the river. These birds were also frequently to be seen on the 
Dalmatian islands, and I noticed one standing on a cliff 
bordering the river Cermanja in the north of Dalmatia. 
HERODIAS GARZETTA. Little Hgret. 
Harly on the morning of April 10th six Little Hgrets 
pitched upon a rock on the shore of Lacroma during a strong 
gale of wind ; and in April single individuals frequently came 
and stayed on the island for a short time. I also saw them 
in the marshes of the Narenta and of the Lago di Vrana. 
Nycticorax EuRoPzuUS. Night-Heron. 
In March one hears almost every morning and evening the 
cries of the Night-Herons as they fly over Lacroma. 
ARDEA RALLOIDES. Squacco Heron. 
On April 4th two were seen sitting on a rock by the shore 
of Lacroma, and on the 22nd I observed some flying from the 
marshes of the Lago di Vrana to feed on the grazing- 
grounds of the horses and cattle. 
ARDEA PURPUREA. Purple Heron. 
On the morning of April 6th a couple pitched in the pine- 
woods of Lacroma and there spent the day. Next day several 
came, all of which selected the same resting-place—a clump 
of tall thick pines at the southern extremity of the island. 
On April 12th more than twenty alighted together, while 
other large flocks passed high over it without settling. I 
also met with the Purple Heron on the river Cermanja and 
at the Lago di Vrana.
