152 . ME. W. P. PYCRAPT ON THE MOEPHOLOGY AND 



present, and bear the same relation to the remiges. Other coverts — t. medioe, miiiores, 

 and marginales — are not distinguishable. 



There is no ala spuria. 



Neither in this, nor in any other species of the Palceogiiathce are there any semi- 

 plumse, plumulEe, or filo plumulse. The absence of these last is of more significance 

 than of the two former. There are no rectrices. The oil-gland is wanting. 



Eyelashes are present and well developed. 



The Rham2}hotheca of the upper jaw is compound, being composed of a small median 

 rhino- and small lateral gnathotheca. The nasal fossa is not protected by the rhampho- 

 theca, but is covered only by the integument. The anterior nares are impervious, 

 slit-like, slope obliquely forward, and placed at the extreme end of the fossa. 



The Podotlieca (fig. 2 a, p. 155) has the acrotarsium clothed, below with broad scutes, 

 above with large granular scales ; the acropodium with scutes. The claw of the inner 

 toe is greatly elongated, to serve as a weapon of offence. 



The wing is not armed with the blunt claw found in many other species. 



C. casuarius heccarii (Sclater). 



The pterylosis of this subspecies agrees with that of jthe typical form C. casuarius. 

 In one specimen I found 6 remiges, the additional quill representing a primary. 



C. casuarius sclateri. 



The pterylosis of this agreed with tlie two foregoing. In one half-grown specimen 

 the apterium spinale could be faintly traced from the inner surface of the skin. The 

 wing bore a long blunt claw. 



C. casuarius salvadorii. 



Apter. s^nnale. — Though not of great extent, in this species was well defined. It 

 extended cephalad as far as a point corresponding with the exit of a vertical line 

 passing through the body from the posterior end of the sternal callosity, and caudad to 

 the middle of the pelvis above the acetabulum. Its total length was about 8 inches, 

 its width about \ inch. 



A. mesogastrcei. — Very narrow, and bounded by degenerate [feathers, indicating a 

 tendency to increase the width of this space, and recalling similar conditions in the 

 Carmat(B. It could be traced backwards to within a short distance of the cloacal 

 aperture. 



A. trunci later ale. — Represented by the naked under surface of the wing. 



Pteryla alaris. — As in C. casuarius. 



The wing was armed with a claw.
