EXTRA-BRITISH ASTBROIDEA. 107 



1. AMPHIORA CRETACEA, n. sp. PI. XXVIII, figs. 6, 6 a. 



Specific Characters. Five (or six) mouth-papillge. Two tentacle-scales. Five 

 arm-spines. Mouth-shields triangular in shape with a curved convex base, a 

 fair proportion of the jaws (oral angle plates) showing on the ventral surface. 



Material. The one specimen known of this species is preserved in the British 

 Museum (Nat. Hist.), no. E. 5059 (Capron Coll.). 



Description. The disc is 3 mm. in diameter. 



There are five (or six) moderately stout blunt mouth-papillas on either side of 

 the mouth-angle, and a triangular papilla situated infradentally. The side mouth- 

 shields are long and narrow, with- proximal and distal sides parallel. They meet 

 in the middle. The extremities of the jaws are very obvious above these. 



The arms are long and slender, and are 2 mm. broad at base. The width of 

 arm close to disc is 1*6 mm. The first under arm-plate is small, with slight 

 re-entering sides and a prominent median groove. The remaining under arm- 

 plates have a pointed proximal apex, and their sides are re-enteringly curved. 

 The distal side is convex. The side arm-plates meet proximally on the under 

 surface in the middle line. 



The five stout tapering spines are rather longer than a joint of the arm, and 

 are situated on a proximal ridge. 



Locality and Stratigraphical Position. Lower Chalk, Folkestone. 



CRETACEOUS ASTEROIDEA AND OPHIUROIDEA FROM 

 EXTRA-BRITISH LOCALITIES. 



The following are the principal species from extra- British localities which 

 have not been mentioned in the previous portions of the Monograph. It will be 

 seen that where accurate information is available, these species are almost entirely 

 identical with British species.

The illustrations given of this species are very beautiful and accurate, and 

 enable one to identify the ossicles ascribed to it as a mixture of ossicles of
