not a simple species, and should, therefore, as such, have a com- 
pound and not a simple name.” The propriety of this must, I 
think, impress every one, but in endeavoring to carry out his plan 
in the present instance I have experienced a serious difficulty. 
In naming hybrid forms Mr. Collett makes use of the generic title 
of the male parent alone, the compound^' part being made up 
from the specific appellations of hoik parents. Thus he calls the 
offspring of the male Ptarmigan [Lagopus alhiis), paired with the 
female Black Grouse [Tetrao tetrix), Lagopus tetrici-albiis, the numer- 
ous recorded facts at his disposal enabling him to decide upon the 
respective specific relation of both parents with almost absolute cer- 
tainty. But in the present case the entire absence of any facts 
bearing upon this part of the problem reduces me to the somewhat 
dangerous limits of mere conjecture, or, what is little better, the 
relative preponderance of specific resemblance exhibited by the speci- 
men before me. Not to weary the reader by a too exhaustive pre- 
liminary discussion of detail, I will restrict myself to the simple 
statement that after careful examination I believe the hybrid 
Grouse about to be described the offspring of a connection between 
Cupidonia cupido, male, and Pedioecetes phasianellus var. colicmhi- 
anus, female, and I accordingly bestow upon it, provisionally, the 
compound name Cupidonia ciipidini-columhiana. 
Distinctive Characters. — Adult male, from a specimen in my col- 
lection, obtained in low^a. Size and general proportions of Pedicecetes 
phasianellus var columhianus. Tail of sixteen feathers exclusive of two 
central projecting ones. Tarsi feathered as in Cupidonia. Neck-tufts 1.50 
inches long. Upper tail-coverts coextensive with the rectrices. Above 
similar to Cupidonia cupido ; wung-coverts (but not the scapulars) white- 
spotted, as in Pedioecetes. Breast and sides ]3arred transversely, as in G 
cupido; abdomen white, sparsely covered wuth obtuse V-shaped spots of 
brown. Head, neck, and throat-markings precisely as in C. cupido. Neck- 
tufts dark brown ; the longer ones not so stiff as those of C. cupido, the 
shorter dull yellow. Tail generally similar in shape and color to that of 
C. cupido, hut with a central pair of elongated feathers “wuth parallel 
edges and truncated ends,” wffiich project .52 of an inch beyond the next 
pair. These projecting feathers are tipped with light hrowm like the other 
rectrices ; suhterminally for, the space of about an inch they are solidly 
black, — anteriorly, with ragged rusty-yellow bars. The outer webs of the 
outer pair of rectrices are irregularly wffiite. The measurements, taken 
from the dried specimen, are as follows: Wing, 8.57 ; tail, 3.25, — tw'O 
central feathers, .52 longer ; bill, depth, .40, length from nostril, .50 tar- 
ns, 2.03 ; middle toe, 2.75.
