24 ^4. E. Vevrill — Additions to the Fanna of the Bermudas. 



Body depressed, broadly rounded posteriorly ; foot broad, the 

 edges thin and undulated. Mantle-lobe over the gill-cavity is short, 

 leaving an open sinus at each end of the cavity. Tentacles and rhino- 

 phores about equal in length and similarly folded, the tentacles 

 broader or more expanded distally. 



Color of upi^er surface pale yellowish gray and brown, or light 

 fawn-color, mottled with yellowish white ; head paler. Under side 

 of foot blue with white spots. 



Length, 60°^'", in life ; breadth, about 30'°™. The shell is narrow, 

 oblong anteriorly, elongated, with a much produced beak, which is 

 tapered but blunt. The sinus is slightly concave and about \ the 

 total length of the shell, ending in a very obtuse angle. The anterior 

 and inner margins are nearly parallel, narrowing slightly anteriorly ; 

 the anterior edges obliquely truncate, with rounded angles.

Fig. 1. — Dolabrifera virens V. About + natural size. 



A rather large, yellowish green species, coyered with small, elon- 

 gated, conical, acute or distally branched papillae. 



Body broad-ovate, broader and well rounded posteriorly ; the 

 whole upper surface of the body and head is covei'ed with conical 

 pai^illse, 1 to 2"^™ long, part of which are acute at tip and part are 

 divided at the end into 2 to 4 small branches. Rhinoi)hores shorter 

 and much smaller than the toitacles, deeply folded and enlarged at 

 the ends. Tentacles very large, elongated, with broadly expanded 

 ends, the edges undulated and thin. Mantle-lobe rather small, nearly 

 semicircular, leaving a small open sinus at each end of the branchial 

 cavity. 



Color above, in life, dull yellowish green, with ill-defined blotches 

 of pale brownish, and with white spots ; the papillae are mosth'' lighter 

 and more yellow ; margin pale bluish with white specks ; under
