16. Canis cancrivorus savannarum, subsp. n. 
a. Ad. ?. No. 230. December 10. Altitude 500 feet. 
“On Savannah.” Type. 
A small delicately-built race of the true C. cancrivorus. 
Size, of an adult female, markedly less than in the corre- 
sponding sex of C. cancrivorus. General colour above coarsely 
grizzled grey with a strong suffusion of buffy, and freely 
washed with black along the middle line. ‘The long hairs of 
the back are black for their basal, middle, and terminal fifths, 
with white subbasal and subterminal rings, though the sub- 
basal ring is sometimes obsolete. The woolly fur is buffy, 
duller and tipped with brown along the back, clearer and un- 
tipped on the sides. Face buffy fawn, with indistinct darker 
markings at the roots of the whiskers and below the eyes; 
forehead and crown more greyish, with a lighter patch above 
each eye. Quter side of ear pale brown, passing basally and 
on the large postauricular patch into clear buffy. Chin 
brown ; throat, chest, and belly white, varied with buffy on 
the sides and across between the fore limbs. Front and 
outer side of fore limbs grizzled greyish buffy; inner side 
clearer buffy to the wrist, the middle line of the palm dark 
brown. Hind limbs similarly coloured, the whole of the 
plantar surface blackish brown. Tail bushy, the hairs of its 
upperside and its tip black basally, white mesially, and with 
a broad black end. Below the hairs are dull whitish buffy 
throughout. 
Skull, on the whole, closely similar to that of C. cancri- 
vorus, but smaller, more lightly built, and the zygomatic 
outline more tapering forward in the region of the orbits. 
Nasals decidedly shorter, barely reaching past the level of 
the anterior edge of the orbit, and falling considerably short 
of the premaxillary processes. 
Dimensions of the type (taken in the flesh) :— 
Head and body 610 millim.; tail 280; hind foot (s. u.), 
dry, 116; ear 63. 
Skull: greatest length in middle line 129; basal length 
120; zygomatic breadth 70; nasals (from bottom of con- 
cavity in front) 88x 10; interorbital breadth 23:3; breadth 
across postorbital processes 35; breadth of brain-case 44; _ 
palate, length 63, breadth across m* 39 ; horizontal length of 
p 12:2, of m* and m* combined 16:5; of m, 14:2, m, 8°8, 
Ms 4. 
This appears to be asmall and brightly-coloured Savannah 
representative of the Cands concrivorus of the Guianan coast- 
lands.
