 intercostal spaces and forming a dense imperforate wall.

The genus Fungia is represented in the collection by 8 large 

 anthocyathi, and 44 trophozooids and anthoblasts. 



There were no living specimens obtained from Funafuti, but the 

 dead coralla of apparently four distinct species were picked up on 

 the outer beaches of the islands, showing that the genus must live 

 in considerable abundance close outside the reef. These specimens 

 are, unfortunately, too much worn to be identified with any certainty, 

 but may be provisionally referred to F. crassa, F. patella, F. discus, 

 and F. tenuifolia.

I have referred three specimens to this species, which were 

 obtained all together in a small pool a few feet across. Among 

 themselves they vary considerably in the perforations of their uuder 

 surfaces and the thickness and spiuulation of their septa. In 

 shape they are more or less round, 11-13 cm. iu diameter, with 

 rather open, oval fossae in the centre.

I have also ascribed to the same species as the above a stunted 

 authocyathus, which was found in the same pool, about 9 cm. in 

 diameter, with a part of the upper surface killed by an incrusting 

 nuUipore, The septa are much thicker than in the preceding speci- 

 mens and have deeper and more regular dentations, while the under 

 surface is almost imperforate. 



In the same pool were obtained 24 tx'ophozooids and anthoblasts, 

 forming a good series to the free anthocyathus. The youngest of 

 these has '24 septa, of which 12 are much the larger and thicker, 

 and are joined by a few synapticula.

A single specimen closely corresponding to the descriptions. 

 The fourth, fifth, and sixth cycles of septa in one part of the 

 corallum, where the edge of the calice has grown somewhat 

 upwards, are characterized by a large, pointed, raised tooth at the 

 inner edge with a deep bay outside. In other parts, where the 

 upper surface of the disc is convex, the tooth is usually present, 

 but less distinct and with no dee]:i bay.
