A. Dipsastrcea denticulata, Blainville, The A. dipsacea of Quoy and Gaymard, 



Man. 373. may be this species. 



Favia denticulata, Ehrenb., G. lix. sp. 4, 



36. ASTHMA PECTINATA. (H. 6f Ehrenberg.} 



A. subglobosa, brunnea. Corallum, cellis 3-6'" longis, scspe oblongis et 

 flexuosis, profundis, intus coronatis ; collibus vix sukatis ; lamellis 

 margine verticalibus. apice truncatis, asperis. 



Subglobose ; brown. Corallum with the cells 3 to 6 lines long, often 

 oblong and flexuous, deep, coronate within ; ridges scarcely sulcate ; 

 lamellse with the inner margin vertical, truncate at apex, rough. 



Red Sea. Ehrenberg. 



This description is taken from Ehrenberg. The species in its 

 vertical and deep cells, coronate within, and the lamellae truncate at 

 apex, is near the versipora, from which it is separated by its entire or 

 scarcely sulcate ridges.

 , Lamarck, 2d ed. ii. 412, No. 16 a. " Stellis margine coadunatis, rigidis." 



37. ASTR.EA DEFORMIS. (Lamarck.) 



A. subglobosa. Corallum cellis 4-6'" longis, angulatis, interdum ob- 

 longis et irregularibus ; collibus angustis, integris ; lamellis alternis, 

 asperis, truncatis, exsertis. 



Subglobose. Corallum with the cells 4 to 6 lines long, angular, 

 sometimes oblong and irregular ; ridges narrow, entire ; lamellse 

 alternate, asperate, truncate, exsert. 



Indian Ocean ? Lamarck. Red Sea. Ehrenberg. 



Lamarck states that this species is near the denticulata in general 

 habit, but differs in having no sulcus to the ridge, or rarely an obso- 

 lete sulcus.
