Knott — On Abnormalities in Human Myology. 413 



Genio-hjoidetis. — I have in a good many cases found this muscle 

 inseparably blended with the lower fibres of the genio-hyo-glossus. 



Mylo-glossus (Eolfincius). — Of this muscle I have met with one 

 example, passing in its usual direction from angle of jaw to side of 

 base of tongue. 



Stylo-glossiis. — In five instances I have found this muscle with an 

 accessory head from the stylo-maxillary ligament. Twice I have 

 found it completely absent on one side. 



Stijlo-hyoideus. — In several instances I have seen the two parts into 

 which this muscle was split by the tendon of the digastric separate from 

 the origin to the insertion. I have seen the muscle inserted into the 

 tendon of the digastric in one case. One instance of complete absence 

 was noted. 



Triticeo-glossus (Bochdalek, Macalister). — This anomalous bundle of 

 muscular fibres I have succeeded in defining but five times in forty- 

 four cases in which it was carefully sought for. This is much below 

 the average of frequency which occurred in the experience of Bochdalek 

 (8 in 22), and Macalister (1 in 6). Professor Krause makes the pro- 

 portion of cases in which it occurs to vary from 17 to 36 per cent. 



Azygos linguae; musculus longitudiyialis linguae inferior medius 

 (Bochdalek). — A small median bundle of longitudinal fibres found 

 between the genio-hyo-glossi muscles in the posterior fourth of the 

 tongue. I have been able to define it in five bodies out of forty- 

 seven in which it was sought for. 



Genio-glossiis accessorius (Luschka). — A bundle of the lower fibres 

 of the genio-hyo-glossus — from lowest part of genial tubercle to hyoid 

 bone. I have succeeded in defining such a bundle as Luschka describes^, 

 separated from the other fibres of the genio-hyo-glossus about once in 

 seven subjects. 



Cephalo-jjJiaryngeus (Sandifort). — Of this anomalous band of muscu- 

 lar fibres I have seen a good many examples: — Three arising from 

 vaginal process of temporal bone ; two from petrous portion of tem- 

 poral bone {fetro-pharyngeus) inside the inferior opening of the carotid 

 canal ; two from the spinous process of the sphenoid ; one from the 

 cartilaginous portion of Eustachian tube {salpingo-pharyngeus). In 

 the majority of instances the fibres became united to those of the 

 superior constrictor of the pharynx. In two examples they could be 

 traced directly to the inferior constrictor. 



Genio-pharyngeiis (Winslow). — A slip closely connected along the 

 anterior part of its course with the genio-hyo-glossus, and passing 

 backwards to the side of the pharynx with the fibres of the superior 

 constrictor. I have found several examples. 



Syndesmo-pharyngeus. — This name has been given to a small fasci- 

 culus of muscular fibres passing from the posterior border of the 

 thyro-hyoid ligament backwards to the median line {linea aJho^ of the 

 pharynx. It bridges over the space intervening between the origins 

 of the middle and inferior constrictors. I have found it twice in 

 forty-seven subjects in which it was specially sought for. 



Levator glandulae thyroideae lateralis. — Under this name Krause
