 the rock in small masses. At other localities on the same moun- 

 tains are found beryls of large size, black tourmaline, ilmenite, 

 and black garnets.

 village. Me., in granite associated with large garnets and rose

Though nearly all the species were already in the Society's

Description of a specimen. Diameter of disc, 35 millim. 

 From outer side of madreporic shield to outer corner of opposite 

 mouth-slit, 16 millim. Width of arm, at base, from 9 millim. to 

 13 millim. Length of arm, measured along the branches, 116 

 millim. Distance from outer side of madreporic shield to inner 

 points of mouth papillae to that between outer corners of mouth- 

 slits, 11 : 5. Madreporic shield very indistinct, oval, irregular, 

 longer than broad. Teeth, tooth -papillas and mouth-papillae stout, 

 regular, conical ; about twenty-four in number ; those near the 

 outer corners of the mouth-slits rather smaller ; most of them are
