CHIONIS MINORo 105 



Scapula is long and sword-shaped. It is flattened from before back- 

 ward near its articulation, and from side to side from its midde third 

 outward, being slightly twisted upon itself. It articulates with the 

 coracoid by a broad oblique head, marked posteriorly by three promi- 

 nences, and measures 2.10 inches in length by an average width of 0.15 

 inch. 



Furculum is moderately stout, U iflstead of V shaped, its sides at first 

 parallel, then curving gently toward each other. It runs backward, 

 with little downward inclination, and its apex is directly beneath the 

 manubrium sterni, falling far short of the apex of the sternal keel. 

 There is no prominent process at the union of its two elements, only a 

 small mass of bone, facing the manubrium. 



Eihs are eight in number, of which all but the first and last articulate 

 with sternum. Splint ribs are distinct, averaging 0.40 inch in length, 

 slightly curved, pointed, and directed obliquely upward and backward; 

 but we cannot say how many there are, owing to the carelessness of the 

 person who boiled the subject. 



Humerus measures 2.70 inches in length; a slender bone, slightly 

 curved, like an italic/. Its head is much expanded and flattened from 

 without inward, covering the region of the joint as with a shield, con- 

 vex externally, concave internally. It is marked by many deep grooves 

 and depressions for muscular attachments, and by a very prominent 

 ridge along its dorsal surface, whereto are attached the tendons of the 

 pectoralis major and minor, latissimus dorsi, and scapular muscles. 



The forearm is slightly longer than the humerus, measuring 2.9 inches 

 from elbow to wrist. The radius measures 2.70 inches, and the ulna 2.80 

 inches. Both bones are rather stout for their length. Just below the 

 carpal joint is given off from the radial side of the carpus a prominent 

 exostosis, knob-shaped, 0.30 inch long by 0.20 inch wide at the base, 

 growing out perpendicularly to the axis of the bone. This knob sup- 

 ports the wing-spur, is undoubtedly bony, but presents no recognizable 

 evidence of independent ossification. The principal bone of the meta- 

 carpus, that representing the middle finger, carries two phalanges, 

 measuring together 1.20 inches. To its ulnar side is attached at each 

 end the metacarpal bone of the fourth finger, which acts as a splint- 

 bone, being quite separate excepting at its extremities. This fourth 

 metacarj)al carries but a single phalanx. The radial metacarpal is a 

 small spicule. 



Femur measures 2.1 inches in length. Trochanter is flattened so as
