sents a specimen nine inches long and four broad, which is much 

 wider in proportion to its length than the limacina.

Fig. 3, Plate 20, may be this species. It is from a specimen deeply concave below, 

 eighteen inches long, and/ three and three-fourths wide, having the spines of the under sur- 

 face very delicate points, and the lamellae above, rarely three-fourths of an inch long. 



4. HERPETOLITHUS STELLARIS. (Ehrenberg.) Leuckart. 



H. oblongus. Corattum radiatum, stellatum ; oririmd mediand valde 

 angustd ; lamellis interruptis, non aperte fasciculatis. 



Oblong. Corallum radiate, stellate ; medial oririme very narrow, 

 lamellae interrupted, not distinctly fasciculate. 



Ehrenberg adds that this species approaches the limacina, but has 

 smaller lamellae, and narrower and shallower oririmes, and the medial 

 as oblique. The length given for a specimen at Berlin, is nine inches. 

 He refers to Esper's figure, plate 73, which has the form of a three- 

 rayed star, each ray about two and a quarter inches wide, and from 

 two and a half to three and one-fourth inches long. The figure is 

 copied by Esper, from Boddaert (Lyst. d. Plantdieren), and is very 

 imperfect. Boddaert states that there are eight or nine small teeth 

 on the upper edge of the lamellae.
