1 . 517. 1 . Catenipora escharoides. (Pag. 127.) 
1 ®. A portion of a hemispheric specimen, giving the usual characters of the species as it occurs in New-York. 
1 b. The base of the same specimen, showing its mode of growth from below, and the increase by interstitial 
cells, which appears like a bifurcation of a single tube. 
1 c. A fragment from a strong growing mass, preserving the transverse striae, and showing tubes somewhat 
larger than the preceding figure. 
1 d. An individual where the growth is more slender, and the reticulate spaces are smaller. 
1 e. A vertical section of the same, contrasting with fig. 1 c. 
1 /. A vertical section of fig. 1 c, showing the transverse septa of the tubes, and also a confused cellular 
structure, which is probably due to crystallization, from the infiltration of siliceous matter into the 
interior. 
1 g. A vertical section of a well preserved specimen, showing the external striated character of the tubes, 
when magnified. 
1 A. A longitudinal section of the interior of several tubes magnified, showing the striae. 
1 i. A figure showing the vertical section of a mass of this coral, where the spaces are filled, and the whole 
intimately combined with the surrounding stone.
