Groinlandicus was dredged in abundance, living, by the writer, in 1871, 

 1872 and 1873, at depths of from about 100 to 313 fathoms; but on the east 

 coast of Hudson Bay, in Richmond Gulf, large living examples of the same 

 species were recently dredged by Mr. Low in from 15 to 25 fathoms. This, 

 no doubt is an extreme case, and conversely it may be mentioned that a 

 brachiopod (Terehratulina septentrional is) which is not uncommon atEastport 

 (Maine) and Passamaquoddy Bay, N.B., in shallow water, has so far been 

 dredged in the Gulf of St. Lawrence only in very deep water. 



During the preparation of this catalogue, the writer has been greatly 

 indebted to Professor J. Playfair McMurrich for notes on some critical 

 species of Zoantharia ; to Professor VV. C. M'Intosh for much valuable 

 infoimation about the Chietopoda : to the Rev. Canon Norman for the 

 identification of several species of Polyzoa : to Dr. W. H. Dall for an 

 expression of his views on some species of Mollusca : to Professor Yerrill 

 and Miss Bush for recent re-determinations of the difficult species of the 

 molluscan genus Bela ; and to the Natural History Society of New Bruns- 

 wick, per Dr. G. F. Matthew, and Professor G. T. Kennedy, for the loan 

 of specimens of mollusca, ttc, from the Bay of Fundy. 



PROTOZOA 

 RETICULARIA (FORAMINIFERA). 



In all dredgings upon sandy or muddy bottoms in this region, the shells 

 of foraminifera are very abundant, though the habits of their living occupants 

 have yet to be studied. Most of these shells occur at all depths, but in the 

 Gulf of St. Lawrence Uvigerina anyulosa, Cristellaria rotidata, Vaginuliiia 

 spinigera, Bulimina aculeata, Valvulina conica, Rliahdani'^iina abyssorum, 

 and Biloculina ohlonga have as yet only been found in very deep water. 

 The types of Litiiolafindens (now called Reopliax findeiis), of Liiuola cassis 

 (now known as l/aplophragminm cassis), and of Hippocrepina indivisa, 

 described by Parker in the Canadian Naturalist and Geologist for June, 

 1870, and in the American Journal of Science and Arts for June, 1872, 

 are all from Gaspe Bay and its immediate vicinity. 



The following is a list of the species that iiave so far been recognized as 

 having been collected in the Gulf of St. Lawrence : 



Family A'ummulinidce. 



Polystomella striatopunctata, F. and M. | Polystomella arctica, P. and J. 



Nonionina scajilia, F. and M.
