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

 sequence of Dr. Pfeiffer, of Cassel, publishing in my name several 

 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. Lyceum. The specimens were probably forwarded un- 

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