61. ASTR.&A FAVOSA. (Lamarck.) 



A. subglobosa. Corallum cellis majusculis, incequalibus, angulatis mar- 

 gine subacuto, parietibus lamettosis, lamettis dentatis. 



Subglobose. Corallum with the cells rather large, unequal, angular, 

 margin subacute, sides larnellose, lamellse dentate. 



East Indies. 



Astrcea favosa, Lamarck, ii. 413, No. 17. Lamarck here separates Esper's Madre- 

 pora favosa (Fortsetz. i. tab. 45, fig. 1) from the favosa of Ellis, which he names 

 dipsacea. He also unites with the favosa of Esper a fossil found near Givet in France. 

 The recent specimens are described as having the cells a little smaller than in the denti- 

 culata, angular and strongly concave, with the margin nearly acute and not bristled with 

 lamellae. " Ces etoiles donnent a la masse 1'aspect d'un gateau alveolaire." (Gault. Ind., 

 back of tab. 19. Schweig. Handb. 419. Blainv. Man. 375.) 



GENOS VIII. MEANDRINA. LAMARCK. 



Astraidce aggregate; discis animalium seriatim gemmantibus et remote 

 vel hand dichasticis, itaque linearibus, sinuosis. Tentacula utroque 

 disci margine seriata. Corolla cellis fossiformibus, et gyrosis ; 

 lamettis tenuibus, usque ad medium septi longiusve productis. ( Gyris 

 latitudine semipollicem non superantibus.} 



Aggregate Astrseidse; disks seriately budding and remotely or not 

 dichastic, and hence linear, sinuous; tentacles forming a series 

 along either margin of the linear disk. Coralla, with trench-like, 

 gyrose, cells ; larnellee thin, prolonged out of the cell to the middle 

 of the septum or beyond. (Gyri not exceeding half an inch in 

 breadth.) 



The Meandrinae are Astrseas, in which the polyp disks and con- 

 sequently the cells are confluent in sinuous lines. They increase 

 by disk-buds, and differ from Astrseas only in the formation of a suc- 

 cession of buds, without an attendant subdivision of the disks and a 

 separation of the polyps. Those species of Astrsea, in which the
