E grandis, convexa, discis compositis, lineatis, meandrinis. Corattum 

 cettd " lata, interdum 5" elongata; extus subleve, vel parce plicatum 

 et kviter striatulum; lamellis longe exsertis (interdum f") et scepe %"

East Indies. Dr. A. A. Gould. 



The large projecting cultriform lamellae give this species a very 

 peculiar appearance. The specimen examined was placed in my 

 hands for description by Dr. Gould, of Boston. 



APPENDIX. Euphyllia Hemprichii. The Strombodes Hemprichii, of 

 Ehrenberg, from the Red Sea (op. cit. Gen. liii. sp. 1), appears to 

 pertain to the genus Euphyllia, though, from the concise description, 

 this opinion is expressed with hesitation. It is thus described : 

 " Pollicaris, solitaria, turbinata, disco semipollicari, parum excavate, 

 stipite tereti curvo, annulis distantibus, membranaceis, concavis alato." 

 Owing to the rings of the exterior, it resembles some Cyathophylla, 

 in appearing to consist of a series of cones inverted in one another.

 sinuose linearibus. Coratta substipitata, convexa; cellis, fossiformi- 

 bus, meandrinis; lamellis crassimis, paucis, sub<Equalibus, fere in- 

 tegris.
