Smittia CANDIDA (Stimpson). 



Lepralia Candida, Stimpson (1853). 

 Smittia Candida, Verrill (1879). 



Grand Manan, " dredged on stones in 35 fathoms in the Hake Bay "' 

 (Stimpson) ; very common in the Bay of Fundy (Packard). 



Smittia trispinosa (Johnston). 



Lepralia trispinosa, Johnston (1849). 

 Smittia trispinosa, Hincks (1880). 



This species was first recognized as Canadian by Sir J. W. Dawson, in 

 1859, from specimens dredged by Dr. Bell, in 1858, off Marsouin. Packard 

 found similar specimens off Caribou Island, in 1860, and Verrill at the 

 Mingan Islands and off Anticosti in 1861. S. trispinosa is now known to 

 be common throughout the Gulf of St. Lawrence, and Sir J. W. Dawson 

 collected specimens of it as far up the river as Murray Bay. It also occurs 

 in the north Pacific, and Dr. G. M. Dawson has dredged it at three localities 

 in the Queen Charlotte Islands. 



It has been found fossil in the Leda clay at Riviere du Loup, by Sir 

 J. W. Dawson. 



Smittia producta (Packard). 



Lepralia producta, Packard (1863). 

 Smittia producta, Hincks (1889). 



The types of L. producta are from near Caribou Island, and the species 

 has since been found at many localities in the Gulf of St. Lawrence by Sir 

 J. W. Dawson, and the writer, and as far up the river as Murray Bay. The 

 species was first described and figured by Packard, as a Lepralia, in the 

 Canadian Naturalist and Geologist for December, 1863 ; and was subse- 

 quently re-described and re-figured by Hincks, as a Smittia, in the Annals 

 and Magazine of Natural History for May, 1889. 



Sir J. W. Dawson has found it fossil, in the Leda clay at Riviere du 

 Loup. 



Smittia globifera (Packard). 



Lepralia globifera, Packard (1863). 

 Smittia cjlohifera, Verrill (1879). 



Near Caribou Island, " frequent, forming frosty white patches. It often 

 encrusts Cellepora?, where the ovicells are much crowded, and the ridges 

 between the radiating rows of cells obsolete. I have dredged it in the Bay 

 of Fundy " (Packard). " Casco Bay to Labrador, common. It is very 

 common in the Bay of Fundy and on the Grand Banks" (Verrill).
