 Hab. Fernando Po. 



The specimen from which the above description was taken was 

 procured at Clarence, Fernando Po, and was the only one that had 

 been seen by the oldest colonist at that place.

 Hab. apud pagum, Port Lokkoh dictum, Sierra Leone. 

 Mr. Fraser observed that considerable interest was attached to this 

 bird, for which he was indebted to Robert Clarke, Esq., Senior As- 

 sistant Colonial Surgeon at Sierra Leone — not only on account of its 

 being a new species of a somewhat restricted group, but on account 

 of its habitat, all the hitherto recorded species of Pitta being from 

 continental India, the Indian islands, and Australia. 



Mr. Thomson, who originally procured the bird, observes in a note, 

 that the Pulih, or Mocking Bird, is only found in the Timneh country ; 

 that its note is exceedingly sweet, and when a Timneh would pay an 

 orator or poet the greatest compliment, they say, ** He is a perfect 

 Pulih." 



It is most closely allied to Pitta brachyura, Auct. ; but differs from 

 that bird in having the bill and feet red, a band over the eye, which 

 is tawny, instead of olive brown ; in the uniform colouring of the 

 primaries, secondaries and tail feathers, the two former not being 

 tipped with white, nor the latter with green ; and finally, in the ab- 

 sence of the red vent. 



The following " Additional Measurements of the Blood- Corpuscles 

 or Red Particles of Mammalia and Birds," by George Gulliver, Esq., 

 F.R.S., were read : — 



" Many observations are yet required to complete our knowledge 

 of the comparative anatomy of the blood-corpuscles. The present 

 contribution contains an account of some observations which I have 

 made since the publication, in the English version of Gerber's Ana- 

 tomy, of my Tables of Measurements of the Blood -corpuscles of 

 Mammalia and Birds. 



" In the present, as in the former tables, the measurements are all 

 expressed in vulgar fractions of an English inch, and as the nume- 

 rator is invariably 1, it is omitted throughout, the denominators only 

 being printed. In each instance the measurements of the common-
