extensor aponeurosis of the little toe, I have seen on several occasions, 

 but I never have found it existing as the tendon of a separate muscle ; 

 it always was an offshoot, commonly from the peronseus tertius, or in 

 three cases from the peronaeus brevis, and as such I have found it pre- 

 sent in Cercopithecus. (Since the writing of this paper I have seen 

 it as a perfectly distinct muscle, arising under cover of peronseus 

 brevis.) 



15. I can fully confirm Mr. "Wood's statement as to the frequency 

 of the existence of the abductor ossis metatarsi minimi digiti of Hux- 

 ley, Flower, and Wood. The latter author was the first to direct atten- 

 tion to it as a human muscle ; but even before the publication of his 

 paper, I have been long in the habit of demonstrating its existence as 

 a slip, separate from the abductor minimi digiti ; indeed I have found 

 it present in nine out of every twelve subjects. 



1 6. A description of a sixth peroneal muscle has been communi- 

 cated to me by Mr. Macmullen, who found a distinct fleshy belly, 

 taking origin from the lower third of the outer surface of the fibula, 

 over the perongeus longus, and winding round the back of the outer 

 malleolus, to be inserted into the posterior and external surface of the 

 cuboid bone. In this subject the peronseus tertius was absent, but 

 the longus and brevis were present and normal. 



1 7. Tibio-fascialis anticus was a muscle found in one subject arising 

 from the lower third of the anterior edge of the tibia, over the tibialis 

 anticus, and passing downwards to be inserted into the annular liga- 

 ment, over the extensor digitorum communis tendon, as well as into 

 the lower border of the deep tibial fascia. 



18. The levator claviculaB of Wood I have only once seen, in the 

 neck of a spare female subject, and under cover of the clavicular fibres 

 of the trapezius, inserted into the posterior border of the outer third 

 of the clavicle. 



19. The levator glanduhe thyroidei of Sommering I have found 

 either as a separate muscle, or as an offshoot from the inner edge of the 

 sterno-thyroid or the thyro-hyoid muscles. 



20. Fibres of a hyo-epiglotticus muscle I have once traced dis- 

 tinctly, under cover of the glosso-epiglottic ligament, from the poste- 

 rior surface of the body of the hyoid bone to the anterior surface of 

 the epiglottis, overlying the so-called epiglottic gland. 



21. Crico-thyroideus posticus (somewhat similar to the kerato- 

 cricoid of Merkel) was a small band of muscle, which arose from the 

 side of the cricoid cartilage, directly below, and extending a little ante- 

 rior to the articulation between the inferior cornu of the thyroid car- 

 tilage and the side of the cricoid. From this origin its fibres ran upwards 

 and forwards, to be inserted into the lower border of the thyroid cartilage 

 (Plate VI., fig. 3, a). It was situated below and behind the normal 

 crico-thyroid muscle, from which it was quite separate, and differed in 

 the direction of its fibres. Its cricoid attachment was external to the 

 outer border of the crico-arytenoideus posticus, with which some of its 

 fibres were slightly connected. The larynx in which this muscle
