18. FUNGIA EHRENBERGII. (Leuckart.) Dana. 



F. grandis, oblongo-elliptica, interdum medio angustior, subtus scepe 

 concava. Corallum lamellis crasse, dentatis, dentibus apice rotundatis 

 et granulosis, intervallis scepius subacutis; oririma ad utrumque finem 

 fere producta : subtus, confertim echinatum. 



Large, oblong-elliptic, sometimes narrower at the middle, below con- 

 cave. Corallum with the lamellae coarsely dentate, teeth rounded 

 at apex, and intervals usually subacute, granulous; oririme extend- 

 ing nearly to each extremity : below, crowdedly echinate.

This species often attains a very large size. A specimen in the Ex- 

 pedition collections, answering very exactly to Leuckart's figure, but 

 with a simple mouth, instead of three, as in his specimen, measures 

 five inches in length, and two and a half in breadth. The teeth are a 

 line long, obtuse and coarsely granulous at apex. Leuckart mentions 

 one ten inches long, and another, six long and two and a half broad. 



j3. gigantea (Plate 19, fig. 12). Other specimens from the Feejees 

 have many of the characters of the above, but differ in the teeth of 

 the lamellae not being granulous, and a little coarser, though of the 

 same shape. One is fourteen inches long, six broad, and three in 

 height. The oririme is nearly two-thirds the whole length of the 

 corallum, and is not subdivided. It is probably distinct.

19. FUNGIA ASPERATA. (Dana.} 



F. grandis, oblongo-elliptica, latitudine triplo longior, subtus concava aut 

 pJaniuscula. Corallum oririma mediana semilongitudinem paulo su- 

 perante, lamellis ruditer spinoseque inciso- dentatis. 



Large, oblong-elliptical, length three times the breadth; below, con- 

 cave or nearly plane. Corallum with the medial oririme a little more 

 than half its length ; lamellae rudely and spinosely inciso-dentate.
