XXXV, fig. la); in large specimens it is fonr feet or more long, and 3 

 or 4'"'" in diameter at the large end. 



Color of small and moderate-sized specimens is translucent milk- 

 white, cream-color, pale tlesh-color, and occasionally pale salmon or 

 pale pink, with the margins paler and more translucent ; larger indi- 

 viduals are generally deeper flesh-color, cream-color, light salmon or 

 ocher-yellow, and occasionally dull gray ; the ca^cal appendages of the 

 intestine and the i*eproductive organs appear as a more opaque 

 yellowish or pale brownish liand along each side, near the pale 

 margins ; the latei-al nerve-trunks are reddish. 



Length of Ordinary adult specimens, in extension, 500 to 1200"""; 

 breadth in middle 15 to 22'""'; some specimens ai*e more than double 

 these sizes. 



Common, burrowing both in sand and mud at and above low- 

 water mark, and in shallow water down to several fathoms in depth, 

 from Florida to Massnclinsetts Bay, and locally found on the coast 

 of Maine. 



It is particularly abundant near low-water mark on the sheltered 

 sandy shores of the New Jersey estuaries ; Long Island Sound ; Buz- 

 zard's Bay ; Vineyard Sound ; Cape Cod ; and at Annisquam, Mass., 

 noith of Cape Ann. I have taken a number of well grown examples 

 at Quahog Bay, on the coast of Maine, where it is associated with a 

 colony of other southern species. I have not found it in the Bay of 

 Fundy, where it is replaced by a closely allied arctic species (C 

 JuscKs). Its southern range is not well determined, but I have seen 

 specimens from Fort Macon, North Carolina, and others from St. 

 Augustine, Fla., and Charleston, S. C, (W. R. Coe). 



The largest specimen hitherto obtained I personally dug from the 

 sand at low-water mark at Great Egg Harbor, N. J., April, 18'72. 

 This one, when extended, was 22 feet long and nearly an inch in 

 breadth, in the middle. It could contract, however, to less than 6 

 feet in length, becoming, at the same time, much broader, thicker, 

 and firmer. This gigantic specimen is, apparently, the most bulky 

 nemertean that has ever been described, though species of Lineus 

 far exceed it in length. 



When preserved in alcohol it contracts very firmly and shows very 

 plainly the contrast between the form of the anterior and middle 

 regions of the body, the latter being decidedly fiat with thinner mar- 

 gins. The head takes various shapes. 



In alcoholic specimens the mouth is usually large and open. 

 Sometimes numerous small whitish papillae, probably containing the
