the animal kingdom ; but the generic and even the ordinal 

 characters are difficult to make out. There are plates, stems, 

 and spines scattered through the stone ; the most perfect 

 consisting of five ambulacral plates and four pairs of pores. 

 Another specimen, though much broken, shows portions of 

 at least twenty ambulacral or pseudo-ambulacral plates, some- 

 what resembling the Devonian Eleacriyius. In some of the 

 calciferous slates from the same series very similar remains 

 occur, but no perfect or nearly perfect specimen has come 

 to hand. Some of the fossils appear to be fragments of 

 cystidea. 



There is nothing improbable in the association of serpuline, 

 molluskan, and echinoderm remains with Eozoon. Speaking 

 of the Canadian rocks, Dr. Dawson refers to fragments pos- 

 sessing appearances highly characteristic of crinoidal remains, 

 and mentions that these and other appearances would indi- 

 cate that in addition to the debris of Eozoon, other calcare- 

 ous structures more like those of crinoids, corals, and shells 

 have contributed to the formation of the Laurentian lime- 

 stones. 



I give here a list of the fossils I have with more or less 

 certainty identified from the calciferous slates and intercalated 

 limestones of the mica and clay-slates of the Caribean group. 

 Small as this list may appear, it is a great advance upon 

 anything previously published as to the paleontology of 

 these rocks. It may be noticed that there is no mollusk in 

 the list, nor have I yet seen any fossil from the Caribean 

 Group (inclusive of the compact limestone) which I could 

 refer with any degree of probability to the subkingdom 

 molluska.
