vures, alternating with luteous ones placed on the folds between 

 the nervures, these preceded by a submarginal series of black 

 spots ; there is a luteous spot on the disco-cellular nervule^ and a 

 faint one of the same hue between the median and radial nervures. 



Head varied with white and black; antennse black, spotted 

 with white. 



Thorax and abdomen yellowish white. 



In the collection of the British Museum. 



Allied to P. Calypso, but easily distinguished by its bright 

 luteous upper wings and the beautiful pearly whiteness of the 

 under surface of the posterior.

Aramus scolopaceus, Bon. (male). 



The oesophagus at its upper extremity is when inflated half an inch 

 in diameter, but is dilated near its middle into an oval crop fully 

 two inches in diameter and three in length ; there is also another 

 slight enlargement immediately above the proventriculus : the total 

 length of the oesophagus from the epiglottis to the proventriculus is 

 thirteen inches. The proventriculus is one inch in diameter and 

 nearly two in length when inflated ; its upper portion is fleshy and 

 thickened, but the coats become thinner as it becomes more expanded ; 

 it is contracted immediately above the stomach. The stomach is 

 moderately muscular and slightly oval. 1 he epithelium is hardened 

 and rugose towards its lower portion. The greatest length of the 

 gizzard is two inches, and its greatest diameter is one and a half inch. 

 The small intestine is a quarter of an inch in diameter, and uni- 

 form from the gizzard to the rectum, and two feet three inches in 

 length. The caeca are of moderate size, and consist of sacs three- 

 quarters of an inch in diameter for two-thirds of their length and 

 contracted to a quarter of an inch before their entrance into the 

 rectum ; they are slightly larger near the middle than at their upper 

 extremity. The right csecum measures three inches in length, the 

 left two and a half inches. The rectum is seven and a half inches 

 in length, and very slightly larger than the small intestine. The 

 cloaca is of moderate size, measuring half an inch in diameter, and 

 with the coats not much thickened. 



The trachea is of small diameter for the size of the bird, and 

 largest at its upper and lower extremities ; at the distance of three 

 inches 'above the bronchise, it is convoluted towards the right side 

 on itself, the form of which will be best explained by the Plate. The 

 bony rings become much stronger and more massive above the 

 bronchiae, and have a larger interval of membrane between them; they
