tion, without cresendo or decresendo effects, and at a distance 
suggests something of a far-off tug-boat whistle. The throat, 
or vocal vesicle, is inflated till about equal to the head in size. The 
toad varies somewhat in color in individuals, appearing quite dark 
in some and paler in others, though the former is always the 
case when not inflated owing to the effect of light. When a 
female happens to approach one of these singing males he will 
immediately hop through the water several times till he suc- 
ceeds in reaching her, and in doing so usually causes quite a 
little commotion by splashing about. Then he jumps upon her 
back to dig his thumbs in her axillaries and there remain. [ 
have not seen them make a call when embraced, and if one 
attempts to lift the male off he will still retain his hold so that 
both may be lifted up simply by securing the male. When 
captured in this manner they will only produce a squeak occa- 
sionally. Sometimes a number of more unfortunate males who 
are unable to procure females will make a concerted move upon 
one should she approach near. The female may frequently be seen 
swimming beneath the water with her lord taking an easy ride. 
To some extent they appear to harmonize well in color with 
their surroundings. Sometimes late in summer, and even into 
October, the males may be heard occasionally giving vent to 
their call. Mr. S. H. Hamilton reports a normal sized jet-black 
example from Beamersville, in Sussex County. It was taken 
amony rocks of the eleGrite syenite class, which were weathered 
very black, and possibly the individual in question is an instance 
of the change in color or pigment due to the environment. 
Messrs. Witmer Stone, H. L. Coggins and J. A. G. Rehn found 
this species about the head of the Batsto River in rgo1, and on 
their trip from Bear Swamp to the “plains” in,1902. Dr. H. A. 
Pilsbry secured examples at Cape May, where I have also 
observed it.
