FORBES O N T H E [May 4, normal disposition of the vessels of the thigh, the presence of the femoro-caudal, semitendinosus and accessory semitendinosus, and the absence of the ambiens 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 Cymbirhynchus. Having lately, through the kindness of M r . Edward Gerrard, jun., become the possessor of a specimen each of Cymbirhynchus macrorhynchus and Euryleemus ochromelas from Sarawak, excellently preserved in spirits, I a m in the position to supplement the above mentioned facts in our knowledge of the anatomy of the Eurylcemidce 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 confirming or modifying previously published statements. As regards osteology, the only point I wish to record is the unforked condition of the manubrium sterni in both species. In this respect they resemble the condition present in Psarisomus, as already Fig. 1. ^••"ilHr-j :?y <L V $ h \ \ k y\ \M J[\\ Vy Jfl w m Left foot of Cymbirhynchus macrorhynchus, viewed from behind, to show the deep plantar tendons, and the vinculum (v.), which the flexor longus hallucis (f 1. h.) sends to the tenrion of the flexor profundus digitorum. The skin has been turned aside, and the superficial flexors removed; the flexor longus hallucis has been cut short above and displaced. noticed by Prof. Garrod. As this feature appears equally in Mr. Sclater's figure of Cymbirhynchus 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. pl. 8. fig. 5), it seems probable that it is a regular character of this family of Passeres, though in other families of that group it seems to be an individual or specific characteristic. |
