protected portions of the surface. There is such a patch on the fragment on the right (see 
fig. 25, Pl. XIII). 
It is to be regretted that we have no knowledge of the kind of base from which these 
spatulate nodules arose. See the account of next form (No. 1904. 10. 17. 37). 
a. Two fragments. Zool. Dept. 1904. 10.17. 36. 
In addition to the foregoing, there are two specimens from Funafuti, both collected and 
presented by Professor W. J. Sollas, which should be mentioned, but are hardly worth describing 
in detail. 
The specimen registered No. 1904. 10. 17. 37 (Zool. Dept.), lay on its side as a detached 
stock, It was bean-shaped, and its rounded thicker side had been uppermost, and the thinner 
notched side undermost, and with the decayed stalk in the centre of the notch. The living 
layer was only alive in patches. The calicles are small, 1 mm., crowded, or slightly pitted. 
The walls are a thin zigzag thread, and the septa form in the typical manner. 
It is impossible to miss seeing a general likeness between the calicles of this detached 
stock and those of the last form, but the skeletal elements seemed less neatly arranged, more 
finely granular, the granules being minute and frosted, giving a soft, woolly appearance to 
the surface. 
It seems just possible that this detached bean-shaped coral, 5 em. high, 6°5 cm. in 
length, and 4 cm. thick, may have been one of the spatulate knobs, broken off, and living as 
a free stock. 
a. Zool. Dept. 1904. 10. 17. 37, 
Specimen registered No. 1904. 10. 17. 38. (Zool. Dept.) is a decayed fragment of a 
massive Porites. Only worn and corroded surfaces are available for examination. The 
trabecule are thick and crowded, making the vertical section nearly solid. In the horizontal 
section the most conspicuous feature is the open reticulum of threads of varying thickness, 
swelling here and there almost into knobs. The walls seem to have been thin, and composed 
of these threads so arranged in a zigzag as to leave the interseptal loculi petaloid. The 
sections of the calicles are conspicuous as rosettes of such interseptal loculi, about 1°5 mm. in 
diameter. 
Lastly, we must call attention to the record * of the collection made by Mr. C. Headley, 
of the Australian Museum, Sydney. Some seven distinct forms are noted, but, having no 
other method than that of all previous coral systematists, Mr. Whitelegge has to attribute 
them without detailed descriptions to so many of what are rashly called “ known species.” 
We have more or less adequate records of some of the forms which Porites assumes, and 
that is all, but I should hesitate before saying that any specimen I had was like any one of 
the earlier described forms. Several very interesting facts can, however, be gathered from 
Mr. Whitelegge’s notes. 
1. A form resembling the “ Porites lichen” of Dana had calicles separated by ridges 
like those of P. Society Islunds 2. This is a rare feature. The size of some of the calicles, 
2°5 mm., suggests the presence of double calicles. See also No. 5, below. 
2. A form resembling the P. lutea of M.-E. and H., the original of which was from 
Tongatabu, and is that preserved as No. Z 191a@ in the Paris Museum, which belonged to
