 The coalescent porcellanous hands on a darker ground constitute 

 the most prominent feature of this pretty species, whose nearest ally 

 is B. trilineatus of Western Australia.

This remarkable shell, reminding one somewhat of a Scalaria, 

 occurs in a semifossil state in the same district where the recent, 

 smaller, and smoother T. marginata, Kilster, appears to be plentiful. 



8. On the Skull of the Chinese Pug-nosed Spaniel or Lap- 

 dog. By Dr. J. E. Gray, F.R.S., V.P.Z.S., &c. 



Dr. W. Lockhart has kindly presented to the British Museum the 

 skull with the atlas vertebra attached, and the penis bone, of a 

 " Chinese pug-nosed Lap-dog, of a breed greatly admired among the 

 Chinese." The skull is peculiar for the very large size, broad ven- 

 tricose and subcubical form ^i the brain-case, for the great shortness 

 of the face, and the shelving, almost horizontal, position of the nasal 

 apertures ; the bones of the face are regular, symmetrical ; the fore- 

 head is rather concave ; the hinder part of the face and the back of 

 the lower jaw are very broad behind ; the nasal bones are well deve- 

 loped, and extend up behind between the orbits nearly to the fore- 

 head ; (he teeth are well developed and in good condition ; the 

 binder parts of the tooth-line are very far apart, from the great breadth 

 of the short palate ; the two hinder upper grinders, which are under 

 the front edges of the zygomatic arch, are placed angularly with 

 regard to each other.
