406 Verrill, Notes on Radiata. 



3d. Although '■'■reticulata " might be a somewhat appropriate name 

 for it if considered a Plexaura, it becomes very inappropriate when 

 referred to a genus in which there are so many species that are ac- 

 tually reticulated throughout, while in this the reticulations are few, 

 irregular, and often entirely absent. 



The following species, which I have not seen, are here referred to 

 this genus with doubt. 



? Gorgonia sanguinea Lam. (Litigorgia (?) sanguinea, 1st Ed.). 



f Gorgonia sanguinea Lamarck, An. sans verteb., 2d edit., p. 495, (Loc. unknown). 

 Plexaura sanguinea Val., Comptes-rendus, sli, p. 12. 

 Leptogorgia sanguinea Bdw. and Haime, Corall., vol. i, p. 165. 



In the latter work this species is described as follows : Corallum 

 rigid, more branched than L. virgidata, and with branches still more 

 slender. Calicles scarcely visible. Color carmine-red. Callao.* 



Leptogorgia (?) arbuscula v. (Litigorgia (?) arbuscula, 1st Ed.). 



Plexaura arbuscula Pliilippi, "Wieg. Arch., 1866, p. 118. 



"PI. 4-6 pollicaris, a basi inde in formam fruticuli divisa, roseo-coccinea ; ramis snb- 

 dichotomis, omnibus libris; ramulis ultimis If lin. crassis." 



Isl. Santa Maria, Bay of Arauco. 



Leptogorgia (?) Chilensis Verrill. (Litigorgia (?) rosea v., 1st Ed.). 



Plexaura rosea Philippi, 1. c, p. 118 {non Leptogorgia rosea E. & H.). 

 " PI. 1-J pedalis, roseo-carnea, subflabellato-dilitata ; ramis virgatis, subnodosis libe- 

 ris ; ramulis ultimis elongatis,. cylindricis, 11 lin crassis, SEcpe 6 poll, longis." 



Algarrobo, somewhat south of Valparaiso, Chili. 



Leptogorgia (?) platyclados v. (Litigorgu (?) plattclados, 1st Ed.). 



PlexoAira platyclados Philippi, 1. c, p. 119. 



"PL roseo, flabellatim ramoso; ramis la tissimis, valde compressis, lorifonnibus." 



Isl. Santa Maria. 



It seems very doubtful whether this species be a Leptogorgia, but it 

 cannot be a Plexaura. 



EugOrgia VerriU. 



Amer. Jour. Sci., xlv, p. 414, May, 1868. 



Coenenchyma composed chiefly of three forms of small spicula, 

 which are naked at its surface. There are two kinds of warty double- 

 spindles, — longer and usually sharper ones, and stouter and blunter 

 ones. These are intermingled with numerous double-wheels, which 

 are usually shorter ; sometimes one of the wheels is smaller than the 

 other, or rudimentary, frequently there are four wheels developed. 



* The original G. sanguinea is, by its spicula, a true Gorgonia (Pterogorgia); the Oallao 

 species is probably distinct and may be one of the following. — Reprint.
