A New Species of Aplysia. Prof. Heilprin exhibited speci- 

 mens of a new species of Aplysia^ or sea-hare, from Little Gas- 

 parilla Bay, west coast of Florida, The animal in general 

 appearance was probably most nearly related to the European A. 

 depilans (leporina), but differed in several well-marked points of 

 structure, notably in color, the position of the buccal aperture, 

 and in the character of the pore connecting with the shell cavity. 

 While in A. depilans the mouth is placed beneath the tentacular 

 lobes i. e., the latter are superior in the Florida species it is 

 central with regard to these organs, the lobes being circumferen- 

 tially connate, and completely encircling the aperture. The pore 

 leading to the shell-sac is minute, and raised on a small papilla; 

 the stellate markings radiating from the base of the papilla are 

 very feeble, and can barely be discerned without close examina- 

 tion. The shell, which is about an inch and three-quarters in 

 length, is horny-calcareous, deeply emarginate, and striated 

 longitudinally and transversely. General color of the animal 

 sea-green, tinged with purple, and irregularly blotched and 

 speckled with spots of lighter color. Length, 7-8 inches. The 

 animal emits a brilliant crimson fluid. It was proposed to name 

 the species Aplysia Willcoxi. 



ALBERT DOD BROWN. 



Announcement having been made that the collection of shells 

 formerly belonging to Albert Dod Brown had been presented to 

 the Academy by his mother, Mrs. Susan D. Brown, Dr. A. E. Foote 

 stated that Mr. Brown, who was formerly Curator of the Prince- 

 ton College Museum, died April 30, 1886, aged 45 years. He had 

 a well-recognized reputation as a student of conchology, botany, 

 and horticulture, the latter years of his life having been devoted 

 to the last-named pursuit. He was one of the founders of the Con- 

 cbological Section of the Academy, and was for jT^ears associated 

 with it as a member. 



The collection now given to the Academy is to be known by 

 his name, but no other condition accompanies the generous gift. 

 A valuable portion of the collection consists of the cabinet of 

 the late Mr. Thomas Bland, including his tj^pes of "West Indian
