Smith and Harger — St. Georges Banks Dredglngs. 55 



The two largest specimens, dredged in 1872, in 28 fathoms, east of 

 Grand Menan, by Professor Verrill, measured 125""" across the 

 disk and tentacles, but their bodies were mutilated. Entire ones 

 of much smaller size were dredged by Dr. Packard and Mr. Cook in 

 110 and 150 fathoms, soft muddy bottom, hauls ^s' and o. The largest 

 of these was 200'""' long, and like other species of the genus, 

 iidiabited a thick, tough, felt-like, muddj^ tube. It was also dredged, 

 in 1873, in Casco Bay, from 7 to 94 fathoms. One of these speci- 

 mens, dredged off Seguin Island, in 70 fathoms, was 450'"'" long, 40""" 

 in diameter, and 175'"'" across the tentacles. A small specimen has 

 been dredged in 18 fathoms off Watch Hill, R. I. 



Epizoanthus Americanus Verriii. 



Plate VIII, figure 2. 



This species lives upon stones as well as upon shells inhabited by 



Eupagiiriis. The specimens from 430 fathoms {g) were on stones, 



while those from 60 and 65 fathoms {s and /') were on shells. It 



ranges from off the coast of New Jersey to the Gulf of St. Lawrence. 



Sponges. 



Most of the sponges obtained have not yet been sufficiently studied to 

 be reported upon, but the two following species are of special interest. 



Hyalonema longissimum Sars. 



G. 0. Sars, on some Remarkal^le Forms of Animal Life from the Great Deptlis off 

 the Norwegian Coast, p. TO, pi. 6, figs. 35-i5, 1872. 



Only a single and somewhat abnormal specimen of this remarkable 

 species was dredged by us in 430 fathoms, but it has since been 

 dredged in considerable abundance by Professor Verrill, in 95 

 fathoms, off Casco Bay, and by Dr. Packard and Mr. Cooke on 

 Cashe's Ledge.* Mr. Whiteaves reports it also from deep water in 

 the Gulf of St. Lawrence.

Plate VII, figure 1. 

 This species, first described by Wy ville Thompson, from specimens 

 dredged in 344 fathoms, off the Shetland Islands, l)y the Porcupine 

 expedition, and dredged by us in 50 and 60 fathoms (hauls e and d), 

 has since been dredged by Dr. Packard and Mr. Cook on Cashe's 

 Ledge and Jeffrey's Ledge in the Gulf of Maine.
