and north to Labrador. In depth it extends down to 150 fathoms, 
and probably much farther. 
MICRODEUTOPUS MINAX Smith, sp. nov. (p. 479.) 
Antennula about two-thirds as long as the body ; first segment of the 
peduncle stout, about as long as the head; second segment a little 
longer and much more slender; third segment nearly half as long as the 
first; flagellum slender, about a third longer than the peduncle; second- 
ary flagellum very small, consisting usually of but oue segment. An- 
tenna about two-thirds as long as the antennula; ultimate and penul- 
timate segments of the peduncle equal in length, and each fully twice as 
long as the antepenultimate; flagellum scarcely as long as the last seg- 
ment of the peduncle. Hands of the first pair of legs in the male greatly 
developed; carpus very large, scarcely longer than the breadth in the 
middle; superior margin strongly arcuate, the inferior angle produced 
into a stout process opposed to the propodus, and the inferior margin 
arcuate and armed distally with two teeth, a large and prominent one at 
the base of the terminal process, the other small, obtuse, or even obso- 
lete; propodus not more than half as long as the carpus, much longer 
than broad, the inferior margin with two broad obtuse teeth; dactylus 
stout, a little shorter than the propodus. Legs of the second pair with 
the basal segment broad and squamiform; carpus elongated ; propodus 
as long as the carpus and as broad as its distal portion, rectangular, 
about two and a half times as long as broad; dactylus short and hooked 
at the tip. In the female the hands of the first pair of legs are only 
moderately developed; carpus broad; propodus scarcely as broad as 
the carpus, rectangular, the palmary margin somewhat oblique, and the 
inferior margin armed with a spine at the obtusely rounded inferior 
angle. In the second pair the basal segment is not expanded but narrow: 
the carpus and propodus much as in the male, except that they are 
clothed with numerous long, plumose hairs. The bases of the first and 
second pairs of caudal stylets are armed with a long, slender, spiniform 
process, arising from the distal end just below the bases of the rami. 
The outer rami of the posterior stylets are a little longer than the inner. 
All the stylets extend to the same point. 
Length, about 4"™. 
Long Island Sound and Vineyard Sound. 
Another species of Microdeutopus was collected in Vineyard Sound, 
but if was not abundant. 
AUTONOE, species. (p. 415.) 
A species belonging apparently in this genus, as defined by Boeck, 
yas common in Vineyard Sound, living in tubes in masses of a compound 
Ascidian (Amouroucium pellucidum Verrill) in 3 to 8 fathoms. It is 6 or 
7™" in length, and in life the antennule and antenne are obscurely 
banded and specked with pink; the body above, except upon the fifth 
segment and the posterior part of the abdomen, is almost black, the
