56 Vaughan Nomenclature of West Indian Corals. 



The latter species is chacterized by having nodules over its sur 

 face, and as LeSueur was an acute observer he could reasonably 

 be expected to have noticed them unless his specimens were 

 very young, but he says nothing from which one would draw 

 such an inference. But in addition to the descriptions, figures 

 are given by LeSueur and these are characteristic of the species 

 that I insist he meant,* and according to my experience of no 

 other. Figure 5b is a cross-section of three collines. I have 

 examined specimens of clivosa but found no such collines, 

 whereas they are characteristic of a common variety of what I 

 am calling viridis. f I see no room for doubting the correctness 

 of my identification. Prof. Verrill in the review has not con 

 sidered that LeSueur attached the name viridis in a varietal 

 sense to a species, and has neglected to make remarks on the 

 figures. I did not use the green color as an aid in identifica 

 tion, in fact I have never alluded to the color of corals in any 

 paper that I have published. 



4. Orbicella annularis (Ell. & Sol.) versus O. acropora^ 

 (Linn.). I used Esper's work in identifying the acropora of 

 LinnsBus. Esper's figure is good, and he states that "Sie kom- 

 men aus den siidlichen amerikanischen Meeren". But as Ellis 

 and Solander had in the interval between Linnaeus and Esper 

 given a definite name to the species, I admit that it is better to 

 use annularis Ell. & Sol., instead of acropora Linn. (Esper). 



5. Porites polymorpha Link, 1807, versus P. porites (Pallas, 

 1766). 



The Madrepora porites of Pallas, as all admit, included 

 several species. Prof. Verrill states that Esper eliminated M. 

 conglomerata and M. arenosa, but he does not give the use 

 made by that author of Madrepora porites. I regret that I did 

 not publish the full synonymy of the species, for that would 

 have shown that the name can be applied only as I have used 

 it, or even in a more restricted sense. The Madrepora porites 

 Esper pi. xxi, is what I have called Porites porites. However 

 Ellis and Solander, 1*786, figured Madrepora porites, the clava- 

 ria of Lamarck, and restricted the name to a particular forma

f Attention is especially directed to pi. xiv, figs. 2 and 5, also pi. xii, 

 fig. 4, of the memoir of Prof. Verrill, previously cited. PI. xiv, fig. 2 

 represents a variety of clivosa, the other figures viridis (cerebrum Verrill).
