POLYZOA. 



A badly preserved specimen of the zoarium of a cheilostomatous poly- 

 zoon that Mr. R. S. Bassler, of the U. S. National Museum, thinks is a 

 Membranipora of the M. memhranacea group, was collected at Brennan 

 Creek, V.I., by the Rev. G. W. Taylor in 1901. 



ECHINODERMATA. 



All the echinoderms from the Vancouver Cretaceous that the writer 

 has yet seen, are a few fragments. 



The Echinoidea are represented by two or three small pieces of the test 

 of a regular echinid, from Departure Bay, Y.I., collected by Mr. Harvey 

 in 1901. These fragments, which in some respects are like portions of the 

 test of a rseudodiadema,shQ^ two vertical rows of small tubercles alterna- 

 ting with the ambulacra. In Pseudodiadema the tubercles are both crenu- 

 lated and perforate, but in the fragments from Departure Bay, although the 

 tubercles are clearly perforate, the outer surface is so much worn that 

 it is doubtful whether they are crenulated or not. 



The Starfishes are represented by a specimen shewing most of the cal- 

 careous plates of one ray of a five-rayed species from Lasqueti Island, 

 collected by Dr. G. M. Dawson in 1885. In reference to this specimen 

 Dr. J. W. Gregory writes as follows, in a letter dated July 18, 1899. "It 

 is no doubt a starfish of the family PentagonasteridiK and a close ally of 

 the genus Callide'^ma. But I believe it to indicate a new genus charac- 

 terized by the smaller size of the marginal plates, and almost equal size of 

 the internal plates. The pedicellarife also are different. If at any time 

 more specimens are forthcoming, shewing especially the external form, I 

 should be glad to do more with the fossil. A very little more would have 

 enabled me to form a tolerably definite idea whether the rays were much 

 prolonged or not." 



The Crinoidea are represented by a single five-lobed joint of the column 

 of a Pentacrinite, and a fragment of the basal portion of the dorsal cup 

 of a Pentacrinite or some other crinoid, both on the same small piece of 

 rock, which was collected at Lasqueti Island by Mr. Harvey in 1901.
