PHALANaEKIDiE. 



An excellent monograph* of the present genus has been written 

 by Dr. F. A. Jentink, of the Leyden Museum. This author, basing 

 his work on the magnificent series there preserved, has made many 

 new and important observations on the distribution, sexual cha- 

 racters, and the variability ia size, colour, and dentition of the 

 species. His careful record of the individual variations in the 

 numbers and situations of the premolars has been of special service 

 to me in my efforts to unravel their complicated homologies. On 

 one point only I am constrained to differ from him, namely, as to 

 the distinctness of Fh. ornatus, united by him with Ph. orientalis, 

 but which, having due regard both to the Leyden series and our 

 own, I feel should be admitted as a separate species.
