Greenport, Long Island (Smith). Long Island Sound, off Thimble 
Islands, 4 to 5 fathoms, among rocks. 
The specimens from Thimble Islands differ somewhat from the original 
description. They were abont half an inch long; moderately stout; 
the foot lanceolate, rapidly tapered posteriorly to a point, but not pro- 
duced far beyond the branchiz, nor slender-pointed; anteriorly the 
angles are somewhat produced, triangular, and pointed, their length 
equal to about half the breadth of the foot. Head rounded ; tentacles 
rather stout, obtuse; the oral longer than the dorsal ones; the latter 
are transversely wrinkled. The branchial papille are fusiform, moder- 
ately stout, obtuse, arranged in about twelve transverse rows on each 
side, forming six clusters, the two rows forming each cluster separated 
by a narrow elliptical naked space, narrower than the spaces between 
the clusters; in each anterior row there are six or seven papille, 
the upper ones larger, the lowest short and blunt. Foot translucent, 
white, with a flake-white streak on the upper side posteriorly ; body pale 
yellowish, minutely specked with greenish and flake-white ; back of the 
dorsal tentacles there is, on each side, an orange patch, and there 
are others along the back; papille dark brown internally, irregu- 
larly specked with flake-white externally, forming toward the end an 
ill-defined white ring; the extreme tips are white; tentacles similar in 
color to the body.
