testimony to the truth of the sentiments conveyed in them, 

 and were unanimously adopted. 



Voted, on motion of Dr. C. T. Jackson, that a copy of 

 the above resolutions be transmitted by the Corresponding 

 Secretary to the family of Dr. Morton and to the Academy 

 of Natural Sciences. 



Mr. Ayres exhibited a specimen of a new species of 

 Psolus recently received by him from George's Bank, and 

 read a description of it as follows. 



P. GRANULATUs Avres. Tentacula ten, short and broad, ra- 

 mose ; of a reddish color, as is also the naked space or neck on 

 which they are supported, with darker, purplish spots. One is 

 much less developed than the others. They are supported by 

 irregular, perforated plates, most numerous toward the tips of 

 the tentacula, much like those of Thyonidium elongatum. 

 Suckers arranged in three rows on the inferior quadrangular 

 space. Lateral rows broad, consisting of about four series of 

 suckers ; intermediate row much narrower. No traces of suck- 

 ers along the other two longitudinal muscles, nor any furrows 

 which might intlicate their locality ; in this feature corresponding 

 with IcEvigafus but not with phantapus, as described by Prof. 

 Forbes. Calcareous deposits of suckers closely resembling 

 those of Cuv. Fahricii. Longitudinal muscles broad, but rather 

 thin. Retractors remarkable for their great length, equalling 

 half that of the entire animal ; and so broad as to cover the 

 oral pouch completely. The two upper ones attached, not to 

 the longitudinal muscles as usual, but to the extremity, in 

 each case, of a transverse muscular branch about half an inch in 

 length. Oral circle similar to that of IcEvigatus. Genital lubes 

 numerous, long, and simple, uniting in a duct about an inch in 

 length, which opens near base of upper tentacula. Digestive 

 tube simple, without muscular stomach, about seven times the 

 length of the animal. Pyriform sac broad, thin, nearly two 

 inches long. Respiratory trees not greatly developed, extending 

 but little over half the length of the animal, and less ramified 

 than in many species. 



The species is identical with the one noticed at the meeting of 

 the Society held March 5th, which was referred with doubt to the
