A. E. Yerrill — Bernindiati and West Indian Reef Corals. 145 



description is very brief and poor, giving no account whatever of 

 the calicles, septa, cost?e, etc. I have seen examples of agaricites 

 growing in tlie same form, but the same is true of A. pmyiirea. 



The name was preoccupied by Edw. and Haime (Corall., ii, p. 84), 

 who applied it to A. cristata Dana {jion Lam.). This last belongs 

 to the frondose agaricites-gyow]). A part of the type is still in the 

 Yale Museum (see p. 146, tig. 6, and pi. xxvii, fig. 5). 



Gregory also makes the same disposition of M. Sancti-Johannis 

 and A. frondosa Duch. and Mich. But Vaughan refers the former 

 doubtfully to agaricites (types not seen). He does not mention 

 frondosa D. and M. ; Quelch thought it distinct. (See p. 149.) 



Mr. Gregory also studied the types of some of the species of 

 Duch. and Mich., at Turin, but unfortunately he does not state which 

 particular species he examined,* so that one cannot tell whose opin- 

 ion has most value, as in the cases cited above, when he and Mr. 

 Vaughan disagree. 



Agaricia crassa Ver., sp. nov. " Pineapple Coral." 



Plate XXX. Figure 6. Plate XXXIV. Figure 2. 



Coral massive, very heavy, forming compact, spheroidal or hemis- 

 pherical masses, up to 150"'" in diameter and 100""" thick, covered 

 with areolated and reticulated collines. 



Calicles deep, rather crowded, 2-3™'" in diametei', with about 

 30-36 rather thin, finely serrulate, scarcely exsert septa ; the 12 

 larger ones vary but little in thickness and alternate with narrower 

 and slightly thinner ones. Many calieles are isolated or in short 

 rows of two to six. The collines, which are variable in height, 

 form curiously and intricately reticulated patterns, consisting of 

 angular or rounded ai'eas, bounded by high, acute collines, each 

 enclosing numerous smaller, sunken areas of various sizes and shapes, 

 bounded by lower, irregularly reticulated collines. Exotheca and 

 Avails, in sections, nearly solid; endotheca cellular, with numerous 

 transverse dissepiments ; columella solid. 



Bahamas (coll. R. P. Whitfield), six or seven specimens, all much 

 alike ; Amer. Mus., No. 514; and Yale Museum, No, 6617. 



* Mr. Gregory states also (op. cit. , p. 2o6) that he examined the collection in 

 the Yale Museum. Unfortunately his visit to New Haven was made in vacation, 

 when I was not in town. Apparently he overlooked various type of Dana 

 which were in the cases that were opened for him. His examinations were 

 very brief. See p. 114.
