faunas far south of their proper limits on the .coast. This third fauna, 

 having its southern outlyers off the New England coast in deep 

 water, has been termed by Dr. A. S. Packard, Jr., the Syrtensian 

 Fauna. 



VIRGINIAN FAUNA. 



The following list includes the species found in this region, whether 

 properly pertaining to it, or having their extreme limits here. 



Polypi. 

 Astrangia Danae Agassiz.

 History, p. 16, figs. 16 to 20. 1865. 



In addition to the localities enumerated in a previous paper.f I 

 have found this species abundant near Thimble Islands, east of New 

 Haven, in ten flithoms, on stony bottom; some patches of the coral 

 are five or six inches across, incrusting stones, etc., and associated 

 with a massive sponge. 



On the Carolina coast, a species very closely allied to this (Astraiv- 

 gia astrmiformis E. & H.) takes its place ; another very similar species 

 occurs in the Miocene deposits of Maryland {A. hella E. & H.) 

 These three forms would doubtless be united into one species by some 

 writers, the distinctions being slight. Similar difierences separate 

 each of the forms from either of the others.

Sagartia Gosse. 



In the Bulletin of the Museum of Comparative Zoology, I have rc- 

 strcted this genus by separating under the name Cereus of Oken, 

 C. hellis of Europe, which was the original type of Oken. To that 

 genus C. sol of the Carolina coast belongs. The genus as restricted 



* The species named by M. Edwards and Haime A. Dante, a year later than the 

 same name was given to the present species, is entirely different; the corallitcs being 

 scattered and connected only at the base. For that species, therefore, I would pro- 

 pose the nume Astrangia Ed wards a, (SQ^ ^ist. Nat. des Coralliaires, Vol. II. p. 

 614).

 of Polypi of this coast is given, with descriptions.
