the finger, except that in many cases the collar-like sheath of the claw 

 is narrower and the claw-plate and claw appear less strongly curved. 



Muscular Attachments. The dorsal and plantar interosseous 

 muscles are attached to the sesamoids and to the plantar side of the 

 base of every proximal phalanx ; in addition, the adductor indicis is 

 inserted on the fibular side of the base of the proximal phalanx of the 

 second digit, and the adductor minimi digit! and the abductor minimi 

 digit! on the tibial and fibular sides respectively of the base of the 

 proximal phalanx of the fifth digit. The common tendons of the ex- 

 tensores brevis and longus digitorum and of the lumbricales are in- 

 serted on the dorsal side of the base of the middle and distal phalanx, 

 the flexor longus digitorum on the base of the distal phalanx, and the 

 flexor brevis digitorum on the base of the middle phalanx.
