Family Fissurellid^. 



104r. Glyphis lineata, Sow. ; G. incei, Reeve. One young speci- 

 men. 



105. Glyphis Watsoni, sp.nov., Biaz. (PI. xiv. fig. 15). 



Shell small, narrow, oblong, rlepressed, anterior slope a little 

 more than half as long as the posterior slope ; sculptured with 

 alternately larger and numerous radiating riblets, interruptedly 

 rayed with light pink ; apex smooth, inclined forward, with a 

 small groove in the centre ; fissure square behind and rounded 

 below, giving it the appearance of a horseshoe ; interior with a 

 septum square across, and the whole of the fissure thickened with 

 white callus, with a deep pit at the fore part behind the septum ; 

 margins of the shell minutely crenulated. 



Long 6, broad 3|, alt. If mm. Two specimens. 



This new species will have to be placed in a new genus, but for 

 the present I have placed it in Glyphis. It comes much nearer 

 to the genus Puncturella in having the apex inclined forward, the 

 fissure horseshoe-shaped, and the interior with a thick septum. 

 The sculpture allies it to Glyphis. 



Specimens have been dredged ofi" Green Point. I dredged a 

 specimen on the 21st November, 1874, off Tacking Point, three 

 miles south of Port Macquarie, in 12 fathoms, rocky bottom. 

 Only about five specimens are known, all collected by Mr. Henn 

 and myself (J. B.). 



106. Megatebennus NiGRiTA, Sow.; i^mMreZ/am^fW^a, Sow. One 



specimen. 



107. Puncturella Henniana, sp.nov., Braz. (PI. xiv. tig. 14). 

 Shell small, white, obliquely conical, apex curved, smooth, 



surface ornamented with thirteen slender radiating ribs not so 

 distinct towards the apex ; interstices smooth, finely striated 

 under a higher power ; fissure elongately ovate, narrow, pointed 

 behind ; septum triangular, slightly inclined forward under the 

 fissure ; margins crenulated at the edge and showing inside the 

 radiating ribs.
