Show 642 MR. A. H. GARROD ON [June 17, portion of the tensor fasciae is very small or absent, and the accessory semitendinosus is present in all but Bulweria bulweri. Species examined. QHstrelata lessoni ? Bulweria bulweri. Prion vittata. Puffinus anglorum. Daption capensis. and some unnamed specimens. The Pygopodes consist of two distinct families. Among the Colymbidee, Colymbus glacialis possesses the ambiens, the femoro-caudal, the accessory femoro-caudal, the semitendinosus, and the postacetabular portion of the tensor fasciae; the accessory semitendinosus is absent. The Podicipidee possess the accessory femoro-caudal, the semitendinosus, and the postacetabular portion of the tensor fasciae ; the ambiens, the femoro-caudal, and the accessory semitendinosus are absent. In these birds the semimembranosus is very thin in Podiceps minor ; in specimens preserved in spirit I have not seen it, probably because it is so slender. Species examined. Podiceps cristatus. Podiceps novee-hollandice. minor. The Alcidce possess the femoro-caudal, the accessory femoro-caudal, the semitendinosus, and the postacetabular portion of the tensor fasciae; the ambiens and the accessory semitendinosus are absent. Species examined. Alca torda. Arctica aile. Uria troile. The Impennes possess the ambiens, the femoro-caudal, the accessory femoro-caudal, and the semitendinosus ; the accessory semitendinosus and the postacetabular portion of the tensor fasciae are absent. In Eudyptes the insertion of the femoro-caudal is much nearer the condyloid end of the femur than to the head. Species examined. Aptenodytes pennantii. Spheniscus humboldti. Spheniscus demersus. Eudyptes catarractes. The Crypturi possess the ambiens, the femoro-caudal, the accessory femoro-caudal (which has a slip arising above the sciatic foramen, found elsewhere only in the Struthiones), the semitendinosus, the accessory semitendinosus, and the postacetabular portion of the tensor fasciae. Species examined. Rhynchotus rufescens. Crypturus sailed. Crypturus obsoletus. noctivagus. |
