development of Actinoloba, of Edwardsia, the fertilization of echin- 
orderms, the development of a planarian, of Spirorbis, of hydroids, 
of Polygordius, of Hexapods, of Limulus, of the lobster, and of Alcy- 
onidium, the relation of the first cleavage plane to the axis of the 
teleosts, the head cavities of the elasmobranchs, the skull and circula- 
tion in the sharks, the formation of the germinal layers in the teleosts, 
the skull of the flounders, the nasal region in teleosts, Kupffer's vesicle, 
lateral line organs in Batrachus, the development of prosobranchs, and 
the morphology of the Algse. An interesting feature was the intro- 
duction of evening lectures once a week. Such lectures were given 
by Drs. Whitman, Minot, Cope, Kingsley, McMurrich, Gardiner, 
Ayers, Wilson, and Watase. 
Among the most pressing needs for the coming season are an addi- 
tion to the laboratory building to afford room for lectures, library, and 
students, a steam launch for collecting purposes, and more books for 
the library.
