Remarks. The double name oi pusilla and piilla was in con-

 species which I had forwarded Mr. Cuming, in Zool. Proc, without 

 knowing that they were already described by me in the Annals of 

 the N. Y. Ivyceum. The specimens were probably forwarded un- 

 der the name given by Dr. Pfeiffer. — Newc.
