214 REPORT OF COMMISSIONER OF FISH AND FISHERIES. [598] 
Many other species were also common, or even abundant, in the various 
localities, and quite a number proved to be undescribed, and therefore 
their descriptions will be found in the systematic catalogue accompany- 
ing this report. Among these were Lycidice Americana, Ninoé nigripes, 
Anthostoma, sp., Acutum, Ammotrypane fimbriata, Travisia carnea, 
Eone gracilis, Brada setosa, Nicomache dispar, Rhodine attenuata, a 
species of Ammochares, Ampharete gracilis, EHuchone elegans, and a 
Species of Nematonereis. 
Several species of Nemerteans also occur on these bottoms. The largest. 
and most interesting is a large species of Meckelia, (M. lurida, V.) This 
grows to the length of 8 or 10 inches, and .25 broad; its color is deep 
chocolate-brown, with paler margins. It generally breaks up into numerous 
fragments when caught. Another species, belonging, perhaps, to the 
genus Cerebratulus, but not sufficiently studied while living, was 2 or 3 
inches long in extension, and .05 to .08 of an inch broad. Its color was 
dark olive-green, darkest anteriorly, the head with a white margin. 
The lateral fosse of the head were long and deep; the eyes incon 
spicuous, perhaps wanting ; proboscis emitted from a terminal pore; the 
ventral orifice, or mouth, placed well forward. Both this and the pre- 
ceding were found at the 29-fathom locality, in sandy mud, but the 
former also occurred in soft mud, in 19 fathoms. 
One of the most abundant Gastropods is Neptunea pygmea, (Plate ’ 
XXI, fig. 115,) which is a rather northern shell, very common in the 
Bay of Fundy. The specimens from this region are, however, quite as 
large as any that I have seen from farther north. The small disk-shaped 
egg-capsules of this shell were found in great abundance early in Sep- 
tember attached to various bivalve shells, as well as to the shells of the 
Neptunea itself. 
Buceinum undatum, (Plate XXI, Fig. 121;) Bela harpularia, (Plate 
XXT, fig. 108;) Lunatia immaculata, (Plate XXILI, fig. 131;) Margarita 
obscura, (Plate XXIV, fig. 156;) Astyris rosacea; and Cylichna alba, 
(Plate X XV, fig. 163,) are all northern shells, which were met with in 
small numbers on the muddy bottoms. 
The Lamellibranchs were quite abundant. One of the most con- 
spicuous is the northern Cyprina Islandica, (Plate XXVIII, fig. 201,) 
which was quite common at several localities, especially in soft mud. 
Many of the shells from the deeper dredgings in this region are north- 
Fig.3. ern and even arctic species, several of which have been 
supposed not to occur south of Cape Cod. Among 
these northern forms are Macoma proxima, of which 
we dredged a few small specimens; Cyclocardia borealis 
jand C. Novanglie (p. 418,) both of which were common ; 
Astarte undata, (Plate XXIX, fig. 203,) which was 
dredged in considerable abundance at several localities. 
s A large proportion of the shells of this species, 
obtained here, were quite different in appearance from the varieties 
that occur in such abundance in the Bay of Fundy. The latter,
