a little raised. Color purple, light red, or yellowish. — Acapulco ;

I have named this fine species in honor of its discoverer, Mr. A. Agassiz, 

 who has greatly contributed to our knowledge of the Marine Fauna} of the 

 Pacific eoast of North America. 



Khipidogorgia media Verrill. 



Fronds Low, broader than high, intermediate between the two preceding 

 speeies in the size of its reticulations; these are usually square or pen- 

 tagonal, quite irregular, generally about one quarter of an inch wide and 

 nearly the same in height. Several large branches usually radiate from the 

 base across the frond. Cells numerous on the sides, a little prominent. 

 Color red with yellow cells, or uniform red or purple. — Acapulco, Mexico ; 

 A. Agassiz, D. B. Vanbrunt.

This speeies is unquestionably P. citrina Dana, but if, as is possible, the 

 Gorgonia citrina of Esper should prove to be a distinct species, the name 

 X. fasciolaris (Eur.) will be next in order. 



It is a smaller and more branching species than X. anceps, forming low, 

 broad corals, branching somewhat in a plane, with much compressed slen- 

 der branehlets, three or four inches long ; these are rarely triangular, — 

 a form very frequent in X. anceps. Color violet, or bright yellow with 

 purple cells. — Florida ; L. Agassiz. — St. Thomas ; Dr. Otis. 



Gorgonia verrucosa Pallas. —Nice; J. Burkhardt. 



Gorgonia rarnulus Val.— Panama; A. Agassiz, J. H. Sternberg. — Acapulco ;

Gorgonia aurantiaca Verrill. 



Syn\ Lophogorgia aurantiaca IIorx, Proc. Phil. Acad. Nat. Sci. 

 18G0, p. 2:13. 



This is a very branching speeies, with short irregular branehlets, ver- 

 ruciform, bilobed cells, and a distinct median groove. Color brick-red, or 

 yellowish. Axis somewhat compressed. — Acapulco, Mexico ; A. Agassiz.
