There are single specimeiis of both sexes of this bird in the Bri- 

 tish Museum, which are the only examples I have yet seen. It 

 may be best arranged near Myrmeciza loricata, the type of the genus, 

 with which it agrees generally in form, although the tail is compura- 

 tively much shorter,

2. On the SPECIES OF CrOCODILUS INHABITING the RIVERS 

 Kw6rA and BlNUE (NiGER AND TsADDa) IN CeNTRAL 



Africa. By Dr. Balfour Baikie, F.R.Geog.S. &c, 



Among the Zoological coUection which I made during my \'isit to 

 the rivers Kw6ra and Binuij in 1854, were several skuUs of Croco- 

 diles, varying in length from 14 to 26 inches. A careful compara- 

 tive examination of these shows them all to be possessed of similar 

 characters ; but on attempting to refer them specifically, I have ex- 

 perienced considerable diffieulty, their proportional measuremeuts 

 not agreeing with any hitherto described. Two African species of 

 Crocodilus are ah'eady kno\vni— C. vulgaris, the Nilotic or Egyptiau
