The Brachiopoda a Division of Annelida. 
By Epwarp S. Morse. 
a meeting of the Boston Society of Natural History, June 1st, 
1870, Mr. Edward S. Morse made a verbal communication on the 
position of the Brachiopoda in the animal kingdom. He referred to 
the branch of Mollusca as it was understood forty peer ago, when, 
misled by external characters, many worms, like Serpula and Spi- 
rorbis, and a group of crustaceans, the — were anes with 
mollusks, and remarked that, from a 
racte rs, these diverse forms had band aiaiai from His pm time, 
Mr. Morse was prepared to state that the Brachiopods were true Ar- 
ticulates, ee not Mollusks, avd that their proper place was among 
the worms, forming a group near the tubi nelids, 
He stated that for the past year he had been deeply engaged in 
the study of the Mos et Pts and more particularly their early 
cina from Callao, Peru, belonging to the Yale ge Museum. 
From these he — studied their early stages ; a he had in 
preparation a memoir upon the subject, he would now. i 
self to the considerations that follow 
He first spoke of the structure and composition of the Brachiopod 
and pointed out the relations between the cecal prolongations 
of the mantle in Terebratula and a similar structure in the test of 
. He had also noticed a marked resemblance between the 
polygonal cells in the shell of a young Discina and a similar feature 
in certain lower crustaceans. The scale-like structure of the test 
of ddotea resembled the scale-like structure in Lingula. The skin 
of Nereis had similar punctures or dots, as seen in Terebratula and 
also in the peduncle of Lingula. He had submitted the shell of 
Discina to bareira tests, and believed it to be chitinous. Gratiolet 
had already given the chemieal analysis of Lingula apenas, a 
ou forty-two per cent. of phosphate of lime,
