No present name is indicated for the last two species. It is hoped Mr. Matthai 

 will supply information on tliem in his next publication. 



Caryophyllia angulosa Quoy and Gaimard, which Milne Edwards and Haime 

 designated as the type of their Leptosmilia, was subsequently named by them 

 Euphyllia gaimardi. This seems to me the same as Dana's EuphyUia rugosa, which 

 must be referred to the synonymy of E. glabrescens (Chamisso and Eysenhardt). 

 Besides E. glabrescens, Milne Edwards and Haime refer to Euphyllia the following 

 species considered by Dana: turgida, rugosa, and meandrina (syn. of fimbriata 

 Spengler). As these species of Dana are reduced to two, glabrescens and fimbriata, 

 one of them must be the type. As it is almost, if not quite, certain that E. gai- 

 mardi, the type of Leptosmilia, is a synonym of E. rugosa, which is a synonym of 

 E. glabrescens, the preference seems to fall on Caryophyllia glabrescens Chamisso 

 and Eysenhardt, which is therefore designated as the type. 



Milne Edwards and Haime refer 8 living species to this genus, viz: E. gla- 

 brescens (Cham, and Eysenh.), E. gaimardi (M. Edw. and H.), E. turgida Dana, E. 

 rugosa Dana, E. striata (M. Edw. and H.),.£'..'' gracilis Dana, E. fimbriata (Speng- 

 ler), and E. plicata (M. Edw. and H.). In the discussion to follow E. gaimardi 

 and E. rugosa are referred to the synonymy of E. glabrescens; while E. turgida is 

 referred to that of E. fimbriata. E.? gracilis Dana is scarcely beyond doubt a 

 synonym of E. fastigiata (Pallas). It appears to me that E. striata is a young 

 colony of E. fimbriata, and that E. plicata probably belongs to the same species, 

 but a restudy of the types is necessary for a positive opinion.

Fig. I. — Reproduction of original figure of Caryophyllia rugosa Chamisso and Eysenhardt. 



Since the volume in which this species was first described is rare, the original 

 figure is reproduced as text-figure i. The exquisite delicacy and the accuracy 

 of Chamisso's drawings (fig. i) are in keeping with the charm of his inimitable 

 story, "Peter Schlemihl." The following is his description: 



"Dichotoma, hinc inde trichotoma. Rami crassitie digiti minimi, vel crassiores, extus 

 glabriusculi vel obsolete striati, versus truncum glabri. Stella concava, centre profun- 

 dissimo, lamcUis margine integerrimis vel obsolete dentatis, alternatim maioribus.
