MR J. W. GREGORY ON THE MALTESE FOSSIL ECHINOIDEA. 629 



Family CASSIDULIDJE. 



Genus Echinolampas, Gray, 1825. 



Species l. Echinolampas kleini (Goldfuss). 

 Synonymy — 



Clypeaster kleini, Goldfuss, 1829, Petref. Germ., p. 133, pi. xlii. f. 5.

 pp. 121, 122. 



Remarks. — This species is recorded by Dr Wright from the Greensand. The 

 identification of the specimen seems subsequently to have caused Dr Wright some 

 misgivings, as the species is not mentioned in his later paper. The Earl of Ducie has 

 kindly lent me the specimen, and I not only question the specific determination, but 

 whether it ever came from Malta. The condition of preservation is very different to 

 that of any Maltese fossil I have seen, and it is probable that it came from Sicily. It is 

 a close ally of the Echinolampas hofmanni, Desor, from the Pliocenes of that island. 

 Dr Th. Ebert,* in his recent elaborate description of this species, makes no mention of 

 Dr Wright's record, so he apparently does not accept it.

Genus Brissus, Leske, 1778. 



Species Brissus cordieri, L. Ag., 1847. 



Cat. rais. Ann. Sci. Nat. Zool. (3), viii. p. 14. 



This species is recorded by M. Desor t from Malta, but I have seen no specimen 

 referable to it. 



IV. — Distribution of the Echinoidea. 



The list in the Table annexed includes 46 species, of which 23 are peculiar to the 

 Maltese beds; in the Upper Coralline Limestone there are 15. species, and in the 

 Greensand 6, of which 2 also occur in the upper horizon. The Blue Clay has so far 

 yielded but one recognisable species, but a fragment of a Clypeaster is of interest, as 

 showing the shallower water in which this bed was deposited. The one species identified 

 also occurs in the Globigerina Limestone, where it is associated with 20 other species.. 

 The Lower Coralline Limestone has yielded 6 Echinoids, none of which occur in the 

 higher beds. Dr Wright mentions several as ranging through the whole series, and 

 though this is not impossible, I have seen no sufficient evidence. And in the south
