18 SOLENODON PARADOXUS. 



for Solenodon cubanus, and the liomology of these two portions with the rhom- 

 boideus anticus and posticus respectively of Gymnura and Centetes is suggested. 

 In Potamogale Dobson found these muscles coalesced to form a single sheet. 



The occipito-scapularis (Plate 5, fig. 4, h) arises along the lambdoid crest 

 for about 10 mm. lateral to the mid-dorsal line. It passes back to the postero- 

 external face of the scapula about 6 mm. below tlie coraco-vertebral angle 

 where it is broadly inserted along the verteljral edge of the scapula. Its length 

 is about 80 mm. 



The sterno-mastokleus (Plate 5, fig. 4, g) takes origin from the ventral sur- 

 face of the presternum, where it is slightly overlapped l\v the ectopectoralis. 

 It passes forward as a muscular band to a tendinous insertion at the lateral 

 extremity of the lambdoid crest just above the ear. This tendon, as in Centetes 

 and Gymnura is united with tlie tendon of the cleido-mastoideus as a common 

 insertion. The cleido-mastoideus (Plate 4, fig. 4, /() takes origin from the antero- 

 external edge of the ventral half of the clavicle. 



The levator claviculae (Plate 5, fig. 4, a) is well developed and takes origin 

 from the atlas only near the median line at the antero-ventral margin. It passes 

 back as a narrow band to a tendinous insertion on the ectal edge of the meta- 

 cromion just back from its tip. 



The splenius arises along the dorsal line from about as far back as the fifth 

 dorsal vertebra. Passing forward, it inserts along the mesial portion of the 

 lambdoid crest from the vertex to just ental of the sterno-mastoid insertion. 

 Anteriorly the portion arising from the first of the cervicals may be more or less 

 readily separated from the posterior part of the nmscular sheet. 



The complexus arises from the transverse processes of the vertebrae from the 

 fifth cervical to the sixth dorsal. It has the usual insertion under the splenius. 

 A lateral and a more median portion may be distingiushed. 



The rectus capitis posticus major arises from just below the top of the neural 

 spine of the axis and passes forward to its insertion beneath the lambdoid crest, 

 in close union with the rectus capitis posticus minor whose origin is slightly 

 more lateral. 



The obliquus capitis superior originates from the tip of the transverse process 

 of the atlas, and goes forward to its insertion below tlie lambdoid crest at a 

 point about 7 mm. lateral to the vertex of the occi])ut. It is also united by a 

 slight raphe to the ecto-proximal portion of the digastric muscle. 



The obliquus capitis inferior is large and arises from the postero-lateral 

 portion of the spine of the axis. Its course is obliquely forward to the posterior 

 side of the transverse process of the atlas.
