36. NOTES ON TWO PIGEONS, JANTHGNAS LEUCO- 
LAIMA AND ERYTHRG@NAS PULCHERRIMA-* 
SINcE my communication to the Society “ On some Points in the Page 367. 
Anatomy of the Columbe,”* specimens of two species of this group 
have died in the Gardens, which deserve a passing note. 
Tantheenas leucolema.—The genus to which this bird belongs has 
been, by different authors, placed sometimes in the Columbine and at 
others in the Carpophagine-section of the family—the number of the 
rectrices (12, and not 14) having made its position uncertain, as its 
general appearance tends to that of the Fruit-eaters. 
From the paper above referred to, the definition of the Columbine, Page 368. 
containing the genus Columba, may be thus stated :— 
Cotumsinz. Columbide possessing an ambiens muscle, intestinal 
~ cxeca, an oil-gland, 12 rectrices, and no gall-bladder.
