normal disposition of the vessels of the thigh, the presence of the 

 femoro- caudal, semitendinosus and accessory semitendinosus, and the 

 absence of the ambiena and accessory femoro-caudal muscles. He 

 also called attention to the unforked condition of the sternum in 

 Psarisomus, this feature resembling that figured previously by Mr. 

 Sclater in Cijinbirhiinchus. 



Having lately, through the kindness of Mr.Edvrard Gerrard, juu., 

 become the possessor of a specimen each of Cymbirhynehus macro- 

 rhynchus and Eurylcenim ochromelas from Sarawak, excellently pre- 

 served in spirits, I am in the position to supplement the above men- 

 tioned facts in our knowledge of the anatomy of the EurylamidiB by 

 describing the syrinx and alimentary canal, previously hardly at all 

 known at all in this group, in these two species, as well as of con- 

 firming or modifying previously published statements. 



As regards osteology, the only point I wish to record is the un- 

 forked condition of the manubrium sterni in both species. In this 

 respect they resemble the condition present in Psarisomus, as already

noticed by Prof. Garrod. As this feature appears equally in Mr. 

 Sclater' s figure of Cymbirhynehus above alluded to, as well as in a 

 specimen of the sternum of that bird in the College of Surgeons, and 

 in Mr. Eyton's figure of Corydon sumatranus (Osteol. Av. pi. 8. 

 fig. 5), it seems probable that it is a regular character of this family 

 of Passeres, tliough in other families of that group it seems to be an 

 individual or specific characteristic.
