The following list pertains largely to a visit I made, with Mr. C. J. 

 Pennock, to ]\Ir. A. D. Poole, at Rehoboth, in late April, 1913. Mr, 

 Poole assisted me in every way to make my stay profitable as possible. 

 On my return to Philadelphia several days were also spent at Lewes. 

 At Rehoboth I visited the off-shore pounds, and thus had opportunity 

 of seeing many interesting species. Several species are new^addi- 

 tions to the State fauna.
