MR. T. ALUS ON" THE SKELETON OF THE APTEItYX. 



523 



Paratraciiys, E. S. 



A genere praecedente differt forma ovali, Jmmeris haud elevatis, 

 tlioracis basi recta, capite piano haud excavato, antennis brevi- 

 oribus, articulis sex apicalibus deutatis atque etiam forma posi- 

 tuque antennarum cavorum. 



This little genus may be distinguished from Trachys, its ally, by 

 the following characters : — Shoulders not raised and prominent. 

 Thorax with its base straight. Antennae short and hairy, with 

 their apical six joints dentate instead of five. Head flat, not ex- 

 cavated. Antennary cavities placed lower down and small. Tarsi 

 with rather longer lamellae. 



N.B. I know of another species of this genus from India. 



Paratrachys heder^e, E. S. iEneo-nigra. Capite thoraceque 

 punctatis, griseo nigroque pilosis. Elytris punctatis, nigro-pilosis, fas- 

 ciis duabus post medium griseis ornatis. Subtus senea, griseo, 

 pubescens. 



Bronzy black. Head punctured, covered with greyish hairs. Thorax 

 with the anterior margin slightly produced; sides rounded; base 

 straight; surface coarsely punctured and covered with black hairs, 

 and with a fringe of grey hairs at the base. Elytra punctured, co- 

 vered with black hairs, and with three grey bands, the first along the 

 base, the second placed near the middle, and zigzag in its form, the third 

 nearly straight and situated midway between it and the apex ; the two 

 lower bands are connected in the middle of each elytron ; apex widely 

 rounded. Beneath bronzy, punctured, grey-pubescent.

On the Skeleton of the Apteryx. 

 By Tuomas Allis, F.L.S. 



[Bead December 3, 1872.] 



There were exhibited two photographs of the skeleton of an 

 Apteryx, which he had prepared and mounted himself; and Mr. 

 Allis pointed out that it differed from the one figured by Pro- 

 fessor Owen (in the second volume of the ' Transactions of the 

 Zoological Society ') in the absence of a nail at the end of the 

 wing, in the greater breadth of the ribs, in the absence of foramina 

 in the sternum and scapulo-coracoid, and in the more complete 

 anchylosis of the sacro-caudal vertebrae — differences most of which 

 might be attributed to the more mature condition of the specimen.
