 describes the liver of the Woodpeckers (of which he examined 

 Gecinus viridis and canus, Dryocopus major, medius, and minor, and 

 Picus martins) as being " immer mit ausgezeichnet Linger darmfor-

Liver, Btomach, duodenum, &c., of Rhamphastos dicolorus, from in front, showing 

 the peculiar intestiniform gall-badder {g. b).

applicable to the last-named species. Garrod also correctly noted, in 

 his MSS„ the " long intestiniform gall-bladder " of Gecinus. The 

 similarity, therefore, in this respect of the Capitonidse ' to the 

 Picidae strengthens the many arguments for the intimate relationship 

 of these two groups. And I may take this opportunity to point out 

 some further peculiarities which these birds have in common with 

 each other. These are : —

 the entire length, or very nearly so, of the humerus, and is inserted

" I us9 this term, with Garrod (Coll. Papers, p. 464) to include the Tou- 

 cans and Indicator, as well as the true Barbets.
