The Cynoidea, including dogs, jackals, foxes, and wolves, form 
a well marked central group, with highly developed convoluted 
czca, placed laterally to the intestinal lumen (Nos. 58-63). 
From this type depart on the one hand the Az/urozdea, includ- 
ing civets and cats, with cecum uniformly present, but short and 
markedly pointed, suggesting the degeneration of a formerly more 
developed structure (Nos. 64-73), while on the other the Arctozdea, 
including bears, weasles, and raccoons, constitute a group bound 
together by many common fundamental peculiarities of structure, 
among which is the complete absence of a cecal appendage to 
the intestinal tract (Nos. 74-87). 
Among the Azluroidea, Hyena occupies an isolated position in 
reference to the cawcum, possessing a well-marked pouch, with 
blunt extremity, resembling the structure in Didelphis (No. 73).
