166 THE MYOLOGY OF THE RAVEN. 



the siipero-external surface of the last rib, which is seen 

 to be immediately beneath it. From these two points 

 its fibres are directed backwards, downwards, and out- 

 wards, slightly converge, then become tendinous, and are 

 finally inserted into the outer aspect of the upper third 

 of the femur, below the trochanter, between the two 

 bellies of the extensor femoris. 



Professor Owen, after completing his description of 

 the three gluteal muscles in the Apteryx, says further 

 that, " A muscle, which may be regarded either as a 

 distinct accessory to, or a strip of, the preceding one 

 [gliitceus minimus], arises immediately behind it from 

 half an inch of the outer and inferior part of the ilium ; 

 its fibres run nearly parallel with those of the glutcBUS 

 minimus, and terminate in a thin flat tendon, which 

 similarly bends round the outer part of the femur, to be 

 inserted into the outer and under part of the trochanter 

 immediately below the tendon of the glnUeus medius. 

 This muscle and the preceding portion, or glutceus 

 minimus, are described by Professor Mayer under the

JVote. — This synonymy must be taken with some degree of 

 caution, for I find it wrong in several instances ; as, for one example, 

 Owen does not call the muscle glutceus quarttis in vol. ii., p. 100, 

 of his Comp. Anat. of Verts., and Selenka is also misquoted for the 

 g. minimus (see Bronn's Klassen, vi. Bd. p. 140). — R. W. S.
