TUNICATA. 



The TUNICATA, both simple and compound, abound in the wains 

 of Long Island, and descriptions <>t' a large number of Bpecies were 

 prepared by Mr. Smith for his paper "On the Molluscs of Peconic 

 and Gardiner's Bays" (Ann. Lye. X. II., N. Y., Vol. \ ii.. April, 

 1860). The difficulty, however, of ascertaining which, if any, are 

 identical with described species prevented their publication at thai 

 time; and for the same reason we think it best to still thWv ii. The 

 number of unpublished species noticed is aboul eighteen, belonging to 

 the genera Asridiivm, Cynthia, Mblgida, Botryllus, Aplydium, and 

 Amorceciv/m or its subgenus Paraacidiwm. In the Natural History 

 of New York, De Kay describes .!.«•/./. ,/ Manhattensis^ De Ka\. 

 but does not expressly say that this species occuis on Long [sland, 

 though it is probable that this is the case. The description 18 80 

 vague a one as not even to fix tin- generic position of the species. He 

 also mentions Boltenia reniformis (Macleay) as found in New Xork 

 Harbor, but the same remark will apply to this. Alex. A.gassiz 

 (Proc. Bost. Soc. Nat. Hist, xi., 17) very fully describes ami figures 



Salpa Caboti, Desor, which he states fco lie ci ion in Long [sland 



Sound, extending its range eastward to Buzzard's Bay and Nantucket. 

 He likewise states that two Bpecies of Appendictdaria, closelj allied 

 to A. furcata and A. longiccmda are extremely common in I.. I. 

 Sound, extending thence to Massachusetts Baj . 



The following dredging lists, prepared bj Mr. Smith in L859, 

 will furnish a clearer idea of the special -tat ion-, the association 

 and relative abundance of our Bpecies, than can be obtained 

 from the detached notice- given of each Bpecies. Kadi lisl is 

 the result of three or lour haul- of tin- dredge, from fifty to 

 three hundred feet of the bottom being Bcraped over each time, 

 and even/ shell found is included, so that ameragi results are 

 obtained. The accented numbers refer to disunited tralv< 



bivalves. The depth- are given in fathom-.
