 Greeuport, Long Island '(Smitm). 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 about half an inch long; moderately stout; 

 the foot lanceolate, rapidly tapered posteriorly to a point, but not pro- 

 duced far beyond the branchiae, 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 papillae are fusiform, moder- 

 ately stout, obtuse, arranged in about twelve transverse rows on each 

 side, forming sis 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 papillae, 

 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; papillae 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 bodv.
