palatines, the head small, the first dorsal over the ven- 

 trals. Atherina is defined by Bonaparte as having 

 very minute teeth, a sharper head and the dorsal over 

 the middle of the length of the pectorals. 



As a matter of fact, there is no important dif- 

 ference in the position of the dorsal, which, in both 

 species, is over the middle of the ventrals when de- 

 pressed, and well behind the tip of the pectorals. 

 Atherina boyeri has a shorter head, more oblique 

 mouth and rather larger teeth. But in this no generic 

 difference appears. Hepsetia like Membras, must be 

 considered as a synonym of A tlierina.

 ISLAND 



Ova and Early Larval Development 



Snow and frost prevailing throughout March, 

 field work during the present year was not resumed 

 until April 7th, observations again being made on 

 the Hudson Estate near Syosset, L. I. The day was 

 sunny, but not warm, with a strong north wind. Mr. 

 R. Deckert, of the New York Zoological Park, 

 accompanied the writer. In the woods there were 

 still patches of snow and ice, and the pools, which had 

 served as breeding places last year and had become 

 dry in summer or fall, were now filled to overflowing, 

 indeed, in some places formed ponds of considerable 

 size and depth. Examination of the flooded regions 

 in the woods soon showed that they contained very 

 little aquatic life, aside from numerous fairy shrimps 

 (Branchippus vernalis) , a few insects, and occasion- 

 ally a woodfrog (Rana sylvatiea) , or a green frog 

 (Rana clarnata). The spring chorus of wood frogs
