A. K Vernll—Bermudian and West Indian Reef Corals. 69 



Among tliose of the section Cceloria are the following : 



3L doidalca (Ellis), E. Indies. 



M. dmdalina {Y).). — Astr(x,a deformis, pars, Dana, {non Lam.) 

 Fiji Is. 



M. spongiosa (Dana). West Indies (?). PI. xii, fig. 3. 



M. pachi/chUa Ehr.= C. labyrinthiformis E. & H., non Linne. 



31. lamellina {Khi:, Y,. 99) + J/, leptochila, Ehr.,= C. Bottai and 

 C. Forskmlana E. and H. = G. Arabica Klz. Red Sea. 



31. laticolUs E. and H., (Corall., ii, p. 415, pi. D4, fig. 4, as C<vIoria). 



31. Sinensis (E. and H., Corall., ii, p. 410, as Ccdoria). China. 



31. strlcta (E. and H., op. cit., p. 417). E. Indies. 



31. astrceiformis (E. and H , op. cit., p. 417). Red Sea. 



3f. Esperi (E. and H., op. cit., p. 417). Red Sea. 



31. leptoticha (Klz., as Cceloria). Red Sea. 



31. laxa Ver., sp. nov. This has broad, distant, and very thin 

 septa, with the edges sparingly and very irregularly toothed, and 

 with the summits broad and rounded or subtruncate. Walls very 

 thin. Valleys deep, mostly sinuous. Columella but little developed. 

 Depth of calicinal valleys, about 7'"'" ; wadth about 5 to 8"'°. Kings- 

 mills Islands. 



M. elegans, 31. deltoides, M. Australiensis (all Rehb.), Australia. 



The following have been referred to Zeptoria by Edw. and Haime, 

 on account of the somewhat lamellose columella :* 



3f. gracilis (Dana). Fiji Is. ; 31. tenuis (Dana). Tonga Is. 



The following are, apparently, more closely related to the typical 

 West Indian species : 



3t. rustica (Dana). Wakes Island. 



31. valida (Dana). Locality unknown. 



M. rudis Verrill^rTI/. phrygia Dana, non Ellis and Sol. 



M. delicatnla (Ortman, 1888). Samoa. 



The following species were referred to Diploria : — 



31. crassior (E. and H., Corall., ii, p. 403). China Sea. 



3f. spinutosa (E. and H., op. cit., p. 404). China Sea. 



He proposes C. Arabica Klz. to include M. leptochila and M. lameUina Ehr., 

 + C. Forskcelana, C. Bottai, and C. subdentata Edw. and Haime, as varieties. 



This shows that the Eed Sea species are quite as variable as the West Indian. 



However, it seems to me undesirable to give a new name {Arabica) to this 

 revised and extended species. It would be better to extend the sense of M. 

 lameUina (Ehr.) so as to include all these forms. 



* The structure of the cohimella is not essentially difPerent in the two follow- 

 ing species (types examined) from that of typical Mceandra, especially that of 

 labyrinthiformis when the latter is poorly developed. It is not a continuous 

 plate, but consists of small, irregular, interrupted laminfe.
