scarcely longer than the segment itself. In these appendages the spini- 
form process from the base is long and simple, not biramous, as in the 
adult, and the lamelle are small, much shorter than this process, and 
the outer one has no articulated terminal portion. The terminal seg- 
ment is as long as the four preceding segments, about as broad as long, 
the lateral margins slightly convex in outline, and each armed with two 
sharp teeth, while the posterior margin is concave in outline, with the 
lateral angles projecting into sharp teeth, between which the edge is 
armed with about twenty small and equal slender spines. 
D.—CATALOGUE OF THE MARINE INVETEBRATE ANIMALS 
OF THE SOUTHERN COAST OF NEW ENGLAND, AND AD- 
JACENT WATERS.—BY A. E. VERRILL, 8S. I. SMITH, AND 
OSCAR HARGER. 
In the following catalogue nearly all the marine invertebrates which 
are known to inhabit the coast between Cape Cod and New York are in- 
cluded, except those belonging to certain groups whick have not yet 
been studied by any one, sufficiently for their identification. Such are 
chiefly minute or microscopic species, belonging to the Entomostraca, 
Foraminifera, Ciliated Infusoria, &e., together with the intestinal worms 
of fishes and other animals. Our sponges, also, have hitherto received 
very little attention, and it has not yet been possible to identify but a 
small number of the species. It is not to be supposed, however, that 
the list is complete in any group, for every season in the past has served 
to greatly increase the number of species in almost every class and 
order, and this will doubtless be the case for many years to come. But 
as no attempt has hitherto been made to enumerate the marine ani 
mals of this region, excepting the shells and radiates, it is hoped that 
this catalogue will prove useful, both to show what is already known 
concerning this fauna, and to serve asa basis for future work in the 
same direction. 
In some instances species that have not actually been found on the 
part of the coast mentioned, but which occur on the shores of Long 
Island and New Jersey, under such circumstances as to render it pretty 
certain that they will also be found farther north, have been included in 
the catalogue, but the special localities have always been given in such 
cases. 
In order not to make the list too long, only those synonyms are given 
which are really necessary to make apparent the origin of the names, 
and to refer the student to some of the best descriptions and figures in 
the works that are generally most accessible, and in which more com- 
plete synonymy may be found. 
For the same reason, in describing the new species, the descriptions 
have been made as brief as seemed consistent with the purpose in view, 
viz: to enable students and others who may not be experienced natu-
