that of ^- * is 1-1, of ^^ 87, breadth of ^--^ 87, length of ^^ is 5-8, 



of jj^. 10"6, and of j^-g 97. Comparing these proportions with those 

 which exist in iEluroids and in the Dogs as exemplified by the 

 Dingo, we find that the cervical region of the Raccoon, 16"9, is much 

 less than that of the Dog, 26-2, a proportion only exceeded by 

 Cynogale (26"6) and Viverricula (27'4) amongst the Viverridce, and 

 not equalled by any Feline form, though it is exceeded by the 

 Hyaenidse (27'9-32'9). The Raccoon's neck is shorter that that of 

 any ^luroid, being most nearly approached by Arctictis, in which 

 it is 18'8 compared with the spine at 100. 



Similarly the dorsal region of the Raccoon (41 -9) exceeds that of 

 most jEluroids, the only relatively longer dorsal regions being those 

 of Paradoxurus (43'8), Arctictis (44'8), Cynogale (43' 1), Suricata 

 (45'4), Galidictis (42'2), and Crocuta (45-6) ; while it may be as 

 small in Genetta as 34'4; that of the Dingo is 46' 1 — the longest 

 of all. 



The length of the lumbar region, which is relatively 287, is smaller 

 than in any Cats (where it ranges from 32'5 to 37'4) and smaller than 

 in any other iEiuroids except Viverricula 23'2, Arctictis 27"2, Cyno- 

 gale 2.5*0, Crossarchus obscurus 26"3, Suricata 25'8, and Crocuta 

 I7'0, which is the smallest of all. In the Dingo it is 21*4. 



The sacrum (12'3) is of exceptional length, being twice that of 

 the Dingo (6'0), while in the Cats it ranges from 7*8 to 5-5. The 

 shortest ^luroid sacrum is that of Cynogale (5"1), and the longest 

 that of Crossarchus ohscurus, 10'9. 



The relative length of the pectoral limb, 74"5, greatly exceeds 

 that of the Dingo (68*4). In the Cats it may range from 61 to 78. 

 It exceeds that of every non-feline iEluroid, being most nearly 

 approached by Proteles, where it is 74 0. 



The length of the pelvic limb, relatively 917, greatly exceeds that 

 of the Dingo, 78"5, and is only exceeded by that of some Cats, where 

 it is 93'8. In non-feline ^luroids it ranges from 55"6 (Firerra) 

 to 79*9 (Suricata) and 80' 1 (Galidictis). 



The relative length of the humerus, 27*4, is greater than that of 

 the Dingo (23"8), and greater than that of any iEluroid except some 

 Cats, where it may be 28*5. In Viverra it is but 1()'3. 



Similarly the radius, 287, is greater than that of the Dingo 

 (24*6), or of any iEluroid, where it ranges from 27*4 (some Cats) 

 down to 13'8 (Viverricula). 



The longest (third) metacarpal, 7' 6, is shorter than that of the 

 Dingo (9'2), orof most Cats, where it maybe 10'9, orof theHysenidae, 

 where it may be (in Proteles) 12'5. On the other hand, it may be as 

 short in the Viverridce as 4'2, which is its relative length in 

 Cynogale. 



The ungual phalanx, 27, is about the proportion of that of the 

 Dingo, which is 2-5 ; that of the relatively longest Viverrine being 

 4"5 (Suricata), and the shortest 13 (Viverra and Genetta). 



The relative length of the skull from the basion to the premaxilla 

 is 28-2, which exceeds that of the Dingo or any Dog or Cat and
