them, and their close resemblance in mer 2 every point of their 
structure to the hippocrepian Polyzoa. Mr. Morse then stated 
that in the evidence already given, he had drawn his conclu- 
sions from alcoholic specimens of Terebratula and Discina, and 
from the papers of Lacaze-Duthiers, Claparéde, Mecznikow, 
Hancock, Huxley, Vogt, Hyatt, Williams, De Morgan and oth- 
ers. He felt the importance of first examining /ingulain a 
living condition before making these announcements and for 
this reason he had recently visited the coast of North Carolina 
for the express purpose of finding if possible the rare Lingula 
pyramidata of Stimpson, first discovered by Prof. Agassiz in 
South Carolina. After nearly a week’s fruitlesssearch he ha 
found it, had studied it alive, and had brought with him living 
examples, which he has the pleasure of exhibiting before the 
Society. 
He would here express his deep sense of gratitude to Dr. El- 
hott Coues, Surgeon U.S. A. at Fort Macon, N. C., and the Com- 
mandant of the Post, Major Joseph Stewart, U.S. A., for the 
constant aid and sympathy rendered to Dr. A. S. Packard and 
himself during their visit there. He would not enter intoa 
description of Lingula as he had already in preparation a me- 
moir upon the subject, but would call attention simply to the 
additional evidence in support of the views siivansed. 
Li 3 found in a sand shoal at lowwater mark, buried 
just below the surface of the sand. The peduncle was six times 
the length of the shell, and was encased in a sand tube differing 
in no respect from the sand tubes of neighboring annelids. In 
many instances the peduncle was broken in sifting them from 
the sand, yet the wound was quickly repaired, and another sand 
case was formed. .

He observed that Lingula had the power of moving over the 
sand by the sliding motion of the two valves, using at the same 
time the fringes of sete which swung promptly back and forth
