400 A. #. Verrill—Marine Fauna of the Outer Banks 
Loripes lens Verrill and Smith, sp. nov. 
Shell white, well-rounded, nearly equilateral, slightly convex, 
thin; lunule small, cordate, deeply excavated ; sculpture slightly 
raised, concentric lines of growth, distinct at the ends, but nearly 
obsolete on the median portion of the shell. Posteriorly the 
outline is more obtusely rounded, so as to form a rounde 
angle with the dorsal and ventral edges: dorsal edge incurved 
in front of the beaks; a faint undulation runs from the beak to 
the posterior angle. Teeth none. Length, 14; height, 12°6™™. 
Stations 865 to 872; 873 to 879, RET on. Also dredged off 
Cape Cod, 1879, in many places (40 to 120 fathoms). 
Modiola polita Verrill and Smith, sp. nov. 
ell thin, translucent, without sculpture; epidermis pale 
yellow, smooth and polished. Umbos prominent; hinge-line 
straight ; posterior end broadly oe compressed ; anterior 
end prolonged decidedly beyond t eak, narrow, rounded, 
Greatest loath, 40; breadth, 21™™. Station 895, two specimens. 
Pecten HES Forbes (?). 
The small species that I refer doubtfully to this species is 
beautifully marbled with brown, red and white. The ears are 
prominent. The lower valve is covered with thin concentric 
riblets, while the upper valve is canceilated with fine radiating 
and concentric raised lines. Station 872. 
EcHINODERMS. 
The star-fishes and ophiurans were | Seepenely abundant and 
beautiful at all the stations, and many species not known pre- 
viously on our coast were = savin! of which appear to be 
undescribed, while others were known only from northern 
Europe, or from the deep pais off Florida. Many of the 
species have only recently been obtained from the ‘northern 
fishing rage off Nova Scotia, and are recorded in this Journal. 
ne new species of Archaster (A. Americanus) was particu: 
larly ech ant, several thousands of specimens having been 
taken ; but the two largest and most beautiful species of this 
genus were Archaster Agassizii (new) and A. Flore. Of 
Odontaster hispidus, over 100 were taken. One of the most 
conspicuous star-fishes was the remarkable Pleraster multipes 
Sars,* one specimen of which was over six inches in diameter, . 
and very thick and heavy. Its color, in life, is rich purple 
above, with the lower side orange, streaked with Bs and 
Hoce Pete yo differs so widely from typical Pteraster as to merit generic 
separa I propose for it the name Diplopteraster, characteriz ayer ecially 
by faviny suckers in four rows, and by having the horizontal radiating interrach 
ial spines of the lower surface imbedded in, and concealed by, a thick skin, w 
adult, (exposed in the young).
