vessels of the branchial sac, sometimes in such quantities as perceptibly 
to distend them and render the branchial sac rather rigid. 
This animal should be considered the type of Stimpson's (1852) 
genus Glandula (see pp. 442 and 574), as it is the species first 
described under that genus, and no other way is apparent for dis- 
tinguishing which of the two species is the type. 
Whiteaves (1874) records this species from the Gulf of Saint Law- 
rence (off the east point of Prince Edward Island, 15 to 20 fathoms, 
sandy bottom). It ranges south to off Nantucket. Type locality, 
Hake Bay, Grand Manan, N. B., 35 fathoms, muddy bottom. 
Range in depth from 30 fathoms or less (in northern localities) to 134 
fathoms (probably to 238 fathoms). 
This species is represented in the Peabody Museum by numerous 
specimens from the following localities. At some of them a large 
number of specimens were obtained and the species is evidently an 
abundant one. 
? Station 2471 (N. lat. 44° 34', W. long. 56° 41' 45", 218 fathoms, gray sand and 
mud), one doubtful specimen, test only preserved. 
Stations 85, 86 (off Chebucto Head, N. S., N. lat. 44° 04', W. long. 63° 27', 
101 fathoms, fine sand). 
Grand Manan, N. B. (collected by H. E. Webster). 
Casco Bay, Me. (60-105 fathoms). 
Station 95 (Hahfax Harbor, N. S., depth not stated). 
Station 2513 (off Nova Scotia, N. lat. 43° 34', W. long. 63° 56' 30", 134 fathoms, 
gray ooze). 
Station 2514 (off Nova Scotia, N. lat. 43° 28' 30", W. long. 63° 57' 30", 126 
fathoms, black mud, broken shells) very abundant. 
Station 67B (N. lat. 43° 25', W. long. 69° 34', 86 fathoms, brown mud). 
Station 13B (Jeffrey's Bank, N. lat. 43° 23', W. long. 68° 30', 105^ fathoms, 
brown mud). 
Station 12B (Jeffrey's Bank, N. lat. 43° 20', W. long. 68° 33', 60 fathoms, 
brown mud). 
Station 16B (Jeffrey's Bank, N. lat. 43° 19', W. long. 68° 49', 79 fathoms, 
brown mud). 
Station 2522 (N. lat. 42° 20', W. long. 65° 07' 30", 104 fathoms, sand, gravel). 
Station 2525 (eastern edge of George's Bank, N. lat. 41° 49', W. long. 65° 49' 
30", 72 fathoms, sand, gravel, and broken shells). 
Station 2.580 (east of Nantucket, N. lat. 41° 25' 30", W. long. 69° 01', 83 
fathoms, sand). 
? Station 895 (N. lat. 39° 56' 30", W. long. 70° 59' 45", 238 fathoms, soft mud), 
one small specimen apparently of this species. 
It seems not unlikely that Pandocia libera Kiaer, 1893 (see also 
Hartmeyer, 1903) is identical with this species, but Michaelsen (1912)
