Family Myriozoidoe. 



Myriozoum subgracile, D'Orbigny. 



Millepora truncata, Fabricius (fide Packard). 

 Myriozoum subgracile (Orbigny) Packard (1863). 

 Leieschara subgracile (Norman) Verrill (1879). 



Abundant and fine at many localities in the Gulf of St. Lawrence, at 

 moderate depths, especially on fishing banks, and often associated with 

 Escharoides Sarsii, Porella elegantula and Celleporaria surcidaris. It was 

 first recognized as a Canadian species by Packard, who dredged specimens 

 on the bank off Caribou Island, in 1862, and who says that it occurs also in 

 the Bay of Fundy and on the Banks of Newfoundland. 



Fossil in the Pleistocene of Riviere du Loup (Sir J. W. Dawson). 



Myriozoum planum (Dawson). 



Lepral ia plana, Dawson (1859). 



Myriozoum crustaceum, Sinitt (1867) ; fide Hincks (1892).* 



The types of L. plana were dredged at Marsouin, by Dr. Bell in 1858, and 

 the species has since been found to be quite common in the Gulf of St. Law- 

 rence. 



It has also been found fossil in the Pleistocene of Riviere du Loup by 

 Sir J. W. Dawson. 



Myriozoum coarctatum (Sars). 



Leieschara coarctata, Sars. 

 Mi/riozoum coarctatum, Sinitt (1867). 



Le Have Bank, N.S., in 45 fathoms, gravelly and stony bottom, common, 

 U. S. Fish Commission, 1872 (Smith and Harger). On the Pacific Coast this 

 species has been dredged at Vancouver and the Queen Charlotte Islands, by 

 Dr. G. M. Dawson, in 1878. 



Schizoporella linearis (Hassall). 



Lepralia linearis, Hassall (1841). 

 Lepralia lineata (Hassall) Packard (1863.) 



Near Caribou Island, rare (Packard). In the Proceedings of the U. S. 



National Museum for 1879 (vol. ii., p. 193) Professor Verrill says that 



Hincks' genus Schizoporella (1879) is synonymous with Escharina, Edwards 



(1835).

* But, in the Annals and Magazine of Natural History for January, 1894, p. 127, (foot 



note), the Rev. Canon Norman says that L. plana is the same as M. coarctatum, Sniitt.
