the middle, and a little concave to either side, so that the lateral 
portions are somewhat narrowed; the plates generally touch 
each other, but scarcely overlap, unless close to the base of the 
arms. The upper surface of the disk has been destroyed in 
the only specimens seen. Diameter of disk about 8 of an 
inch; length of longest arms (broken at the ends) 4 inches. 
Color in alcohol uniform light yellowish, when living tinged 
with greenish. 
Off Thimble Islands and Savin Rock, near New Haven, in 8 
to 6 fathoms, muddy bottom, living buried in the mud with one 
arm thrust out of its burrow. 
I have been aware of the existence of this species for several 
years, having on several occasions dredged a single detached 
am, but it was not until last autumn that I succeeded in obtain- 
ing a specimen with the disk, and even in this the covering of 
the dorsal side was destroyed. 
_ It is somewhat allied to A. gracillima (Stimpson), of S. Caro- 
lina, and has similar habits. The latter has more slender arms, 
four or five arm-spines, and different mouth parts.

lighter below. 
The arms are very long and slender. One of the largest has 
the arms 6 inches long, and the disk 4 im diameter Th 
sealing of the disk is variable, and generally coarser than in 
- Lyman’s type specimens. The radial shields are usually in 
contact. The under arm-plates, near the base of the arms, are 
emarginate and slightly bilobed.
