and often drifted down to lower levels. On the Orphan Bank, as many as 

 from 50 to 100 perfect and fresh (if not living) specimens were brought up, 

 in 1873, in a single haul of tlie dredge, and elsewhere they are equally 

 abundant. The types of C. surcularis were dredged by Packard, in 1860, 

 off Caribou Island, on stones and shells (not " stems and cells," as inadver- 

 tently printed) "in company with Eschara;." Hincks, in his History of the 

 British Marine Polyzoa, includes G. surcularis, Packard, with a query, 

 among the synonyms of Porella compressa (Sowerby). But, as there seems 

 to be some uncertainty in this reference, it is thought desirable, for the 

 present, to retain Packard's specific name. 



In a fossil state, P. surcularis has been found by Sir J. W. Dawson in 

 the Pleistocene deposits at Riviere du Loup.

Two fine examples of this species were dredged on the Orphan Bank by 

 the writer in 1863; and one specimen, in 56 fathoms, stones and coarse 

 sand, eight miles to the S.E. of Bona venture Island, in 1872.

Gulf of St. Lawrence (Hincks, 1892) who writes thus concerning it. 

 " Amongst the St. Lawrence dredgings the true typical form is not by any 

 means common ; the species is represented chiefly by the variety porijera 

 of Smitt. One specimen has occurred to me which, in addition to the 

 ordinary characteristics of S. Landsborovii, is furnished with the large spat- 

 ulate avicularia, which are rarely developed and always in connection with 

 the osecium."*
