Anticostiensis, Billings, is not generically separable from Syringophyllum, 

 and must stand as Syringophyllum Anticostiense, Billings, sp. (3.) 

 Having obtained lately much material of S. organum, Linn., in Russia, 

 I have worked out the genus Syringophyllum, and find it to be an ally 

 of Chonostegites, .E. & H., and Thecostegite.t, E. & H. Indeed, I am 

 doubtful if Syringophyllu7n and Chonostegites can be regarded as generi- 

 cally separable at all. These genera, viz., Syringophyllum, Chonostegites 

 and Thecostegites are all related to Syringopora, and form a kind of 

 intermediate group between the Favositidfe and Syringoporidas. 



ECHINODERMATA. 

 CRIXOIDEA. 



No crinoids with any portion of the calyx preserved have yet been col- 

 lected in place from the Winnipeg or Red River limestones, so far as the 

 writer is aware, though a good specimen of an apparently new species of 

 Saccocrinus, with the dorsal cup and portions of the arms preserved, in a 

 loose piece of limestone probably of Silurian (Upper Silurian) age, was 

 picked up at Cat Head by Dr. Selwyn in 1873. 



A few badly preserved portions of columns of apparently two or three 

 genera of crinoids were collected at Inmost Island by T. 0. Weston in 

 1884 ; at the same island and at Snake Island by D. B. Dowling and L. 

 M. Lambe in 1890 ; and at Cat Head by Mr. Dowling in 1893. Most of 

 these are scarcely determinable, even generically, but some of those from 

 Inmost Island appear to be referable to Olyptocmius or Schizocrinus. 



CYSTOIDEA. 



Glyptocystites. (Species undeterminable.) 



A few calyx plates of a species of Glyptocystites, which Mr. E. Billings 

 said are '-closely allied to his G. multiporus," were collected by Pro- 

 fessor Hind in 1858, at Grindstone Point, as previously stated on page 

 132, and similar plates were collected at the same locality by Mr. Weston 

 in 1884, and by Mr. Tyrrell in 1889. Detached calyx plates and speci- 

 mens apparently referable to the same species, with the whole or part of 

 the column and two or three of the plates of the basal portion of the 

 calyx preserved, though the whole of their outer surface is much water 

 worn, were collected at Deer Island by Mr. Tyrrell in 1889. 



ASTEROIDBA. 



An imperfect and obscure specimen of a protasteroid starfish was col- 

 lected at Cat Head by D. B. Dowling and L. M. Lambe in 1890, on the
