the more dense black pigment is absent. Now 

 supposing this black pigment to be completely 

 wanting, the result would be a salamander similar 

 to that which we obtained at Oohasset, Mass. I 

 have no doubt, judging from similar cases, that a 

 single unit pigment character has been lost with 

 this, at first sight, rather startling result. While 

 the common term albinism and melanism have one 

 a latin and one a greek origin, I presume for the 

 sake of euphony that this predominance of red pig- 

 ment might well be called erythrism. The specimen 

 is No. 3527 of the Amphibian Collection, Museum 

 of Comparative Zoology, Cambridge, Mass.

NOTE ON THE SWAMP TREE TOAD 



fPSE UDA CRIS TBISE h'TA TVS) 



But few definite records have been given for 

 this interesting little amphibian in the Middle 

 States. In New York it does not appear to have 

 been noticed except in the southern part of the 

 state. In New Jersey it has been reported from 

 Signac, Plainfield and in Gloucester County. In 

 Pennsylvania it has been found in the lower part 

 of Chester County, and at Pine Grove in Cumber- 

 land County. I am now able to add another record 

 based on two living examples in my possession, 

 received from M. E. S. Mattern, who secured them 

 in late April, along Lizard Creek, near Bowmans 

 Station, in Carbon County. In Maryland it has 

 been obtained at Jennings, as reported in Copeia,
