50 THE NAUTILUS. 



brachiopod, Terehratnllna septeittrio)iali--<. The best bracbiopod 

 ground, however, has been ruined, by the dumping upon it of blue 

 clay dredged from Luber Narrows. 



The best hauls were made on a moderately soft bottom of mingled 

 mud and sand, wbich was literally filled with dead and living shells 

 of Cyclocardia boreuU><,A><iarte undata, Adarte crebricodata, Cardium 

 pinnnlatum, Sipho pygmoeus, Dentalimn driolotum and many others. 

 Here also were obtained numerous brittle stars, OphiophoU", and the 

 Astrophyton Agamzii, which came up clinging to the outside of the 

 net, nearly as often as inside. AVben the dredge landed in soft mud 

 it brought u]) sucb shells as Leda tennl^-vlcata, Nuenla temiU, Cre- 

 nella glandula, Yoldia mpotilla and Cryjitodon Gouldii. 



Shore collecting at Eastport is sure to prove successful. Ordinary 

 tides rise and fall eighteen feet, and at low^ tide a large area of shore 

 is uncovered. Purpura htpUlu^, Acmcea tedudinali^ and the various 

 Littorinas, common all along the New England shore, are here of 

 much larger size than in Massachusetts. Buccinum nndntum is 

 everywhere seen at low water mark, and bunches of its yellow' Qgg 

 cases are fastened to the rocks in abundance. Underneath stones 

 are myraids of crawling things not well known to a conchologist, 

 but nevertheless interesting. In the larger rock pools every stone 

 hides specimens of Chiton marmoreu-s and Chiton albuf, Saxicava 

 rugosa and Margarita helicina are common and the bottom may 

 fairly bristle w'ith the spiny sea urchins. 



The enthusiastic collector will understand my pleasure when a 

 critical examination of my gathered treasures revealed about 

 seventy-five species of shells, fifteen of which had not previously been 

 represented in my cabinet. My companions, more interested in 

 other invertebrate forms, were also quite successful. Add to this, 

 the fact that we were in the coolest place in the country, wearing 

 light overcoats many evenings while everybody at home Avas swelter- 

 ing in torrid heat, and we may look back to our Eastport trip as 

 favored by fortune and replete with pleasure.
