Hab. Island of Chiloe ; Cuming. 



Chiefly remarkable for its elevated cap-shape. Fig.

another.

 gatd, vertice sitbcentrali ; appendice inlernd cyathi-

Hab. Panama and lieal Llejos ; Cuming. 



Distinguished from C sciitellatum, to which it is very 



nearly allied, by the sharply angular development of the 



Fig. 1 d, e,f, g. (Mus. Cuming.) 

 These specimens are figm-ed to illustrate further varie- 

 ties of C. scutellatmn, described at Plate I., having the ribs 

 more spread and more grooved and red-dotted.
