The maritime region along the shore of Long Island Sound 

 produces a large number of littoral species, but some which one 

 would expect are not yet discovered. Arenaria peploides, which, 

 by the way, is given in the old Catalogue, is not known on the 

 Connecticut shore, though common on the Long Island shore of 

 the Sound, and occurring at Watch Hill, while Rumex maritimus 

 and Ranunculus Cymbalaria are unknown here. Two of our sea- 

 shore plants, Ghenopodium leptophyllum and Panicum amarum, 

 reappear in Colorado. 



Special localities, which richly repay the collector's search, are 

 the Maltby Park region, extending into the boundaries of West- 

 ville, Woodbridge Glen, Saltonstall Lake and Ridge, and espe- 

 cially Paine's Hole on Mt. Carmel, and the ravines leading from it 

 down both the northern and southern sides of the mountain. For 

 more distant excursions, the Meriden Hills, the borders of Litch- 

 field pond, and the shores of the Connecticut river are especially 

 worthy of careful search. 



Though the Musci and Hepaticse of this region prove to be 

 more numerous than I had supposed, yet it can not be doubted 

 that many species in both these orders are yet to be detected. 

 In the former order Schimper's latest arrangement has been 

 followed, and in the latter the arrangement given in Austin's 

 Hepaticae Boreali-Americanse. The larger algae have been dili- 

 gently collected, but as the less conspicuous species have not 

 been carefully studied, it has been thought best to omit the whole 

 Class. Very little has been done as yet in the study of our Lichens 

 and Fungi ; but it may be well to notice that the rare Hydro- 

 thyria venosa is plentiful in a rivulet on the north side of Mt. 

 Carmel, and the curious Mitremyces lutescens is found in a bit 

 of swampy woods at the southern foot of Mill Rock. 



In concluding this introduction I may be allowed to say that 

 while I have gladly rendered what assistance I could to the 

 Editors of this Catalogue, it is truly their own work, and to them 

 belongs whatever credit it may receive. It is also a great 

 pleasure to have been able to point to my venerable friend and 

 predecessor, Dr. Eli Ives, as the discoverer of some of our most 

 interesting species, and thus to connect with the present effort 

 the honored name of one who belonged to a former generation.
