INHERITANCE OF COAT-COLOR IN CATS 547 
The same male was crossed (47) with a blotched blue and 
cream (13) (A.b.m.Yy). There resulted two males—one maltese 
(a.b.m.y) and one cream (b.m.Y); and three blotched blue and 
cream (A.b.m.Yy) females. 
Summarizing crosses of ‘yellow’ males (YX —) by ‘tortoise- 
shell’ females (YX yX), we have four matings giving three 
‘black’ males (yX —), three ‘yellow’ males (YX —), four 
‘yellow’ females (YX YX), and four ‘tortoiseshell’ females 
(YEX syaXe)). 
The long-haired cream male (8) (a.b.m.Y) mentioned above 
was crossed (32) to a yellow-eyed white cat (22). There were 
produced one white male, one white female, one cream female 
(B.m.YY), and one blue and cream female (a.B.m.Yy). Since 
a cream kitten as well as a blue and cream was produced, it is 
probable that the yellow-eyed white was gametically a tortoise- 
shell. 
Dr. C. C. Little has very kindly supplied me with data in 
regard to an anomalous cream female (23) which breeds like a 
tortoiseshell. This female he has given to me along with three 
of its offspring. She has, while in my possession, produced four 
kittens by her cream son. They are two cream females, one 
cream male, and one maltese male. The maltese male would of 
course not be expected from a mating of two yellows. The un- 
der parts of the anomalous female are white. The upper parts 
are entirely cream and show the blotched pattern very plainly. 
No trace of black pigment can be found, although I have exam- 
ined samples of the hair from various parts of the body under the 
microscope. . 
The following gives in detail the offspring from this anoma- 
lous cream female. The unexpected progeny are recorded in 
italics. 
When crossed with (42) a dilute blotched male (A.b.m.y), she 
produced two males—one blotched maltese (A.b.m.y) and one 
maltese (a.m.y); and one blotched blue and cream female 
(A.b.m.Yy). 
When crossed with (39 and 40) an intense striped male 
{A.B.M.y), she produced in two litters two males—one orange
