 , Blainville, Man., 337 ; his figure 3, Haliglossa limacina, Ehrenb., G. xv. sp. 2, 



pi. 51 , is from a worn specimen of one of Herpetolittia limacina, Leuckart, op. cit. 56. 



2. HERPETOLITHUS INTERRUPTUS. (Ehrenberg.} Leuckart. 



H. obtongus, convexus, subtus concavus. Corattum lamellis inaqualibus, 

 fasciculatim interruptis, oririmd mediana nee media. 



Oblong, convex, and below concave. Corallum with unequal lamellae, 

 fasciculately interrupted, the medial oririme not in the middle. 



This species is described by Ehrenberg from a specimen, in the 

 Royal Museum at Berlin, ten inches in length. He refers to figure 

 5, tab. Ill, of Seba. This figure represents a very convex species, 

 eleven inches long, and nearly six broad, with the margin undulate. 

 The lamellae are half to two-thirds of an inch long, and finely denti- 

 culate, and are much more crowded than in the limacina, from which 

 it is distinguished also by its great breadth and convexity. The 

 locality is not known.

3. HERPETOLITHUS FOLIOSUS. (Ehrenberg.) Leuckart. 



H. oblongus, concavus, subtus concavus. Corallum oririmd composita 

 mediana, etiam serie utrinque laterali. 



Oblong, convex, below concave. Corallum with a medial compound 

 oririme, and a lateral series on either side. 



This description by Ehrenberg, from a specimen in the Royal Mu- 

 seum at Berlin, is insufficient for distinguishing it, as an imperfect 

 lateral series may be observed in the limacina. The specimen was a 

 foot in length. Fig. 3, tab. Ill, of Seba, to which he refers, repre-
