84 A. JEJ. Verrill — BermucUan and West Indian Reef Corals. 



Var. cohnnellaris V., nov. 



Form as usual. Septa numerous, crowded, much thickened toward 

 the base and very strongly hispid laterally, edges roughly serrulate 

 and lacerate. Columella highly developed, broad, trabecular or 

 finely lamellose, the lamellae often largely coalescent and rough on 

 the surface. Valleys usually wide and open. Collines either single 

 or double, often sulcate. This is near var. his^nda (Ehr.), in the 

 hispid character of the septa.

Var. angusta of Dana, p. 196, I have not seen. It may have 

 been based on a young example of M. labijrinthiformis.

Although this species has the aspect of a J^avia, near JF". fragum, 

 when the calicles are mostly simple and elliptical, other specimens, 

 and often even different parts of the same specimen, have more or 

 less elongated, narrow cells or valleys, with several indistinct actinal 

 centers, nearly as in 31. Agassizii and parts of M. clivosa. These 

 short valleys are often curved, or bent a little in sigmoid shape, 

 but are not sinuous. They are then separated by small, narrow, 

 solid collines. 



It is evidently closely related to M. varia, but has much narrower 

 calicles and valleys, and still more of the valleys are circumscribed. 

 The septa are thinner and more numerous, rather regularly serrulate.

Vaughan (op. cit., 1901) thinks that this species is not distinct 

 from Favia gravida Ver. It seems that they must be referred to 

 distinct genera. (See p. 91.) I have figured one of the types. 



Subfamily Trachyphyllinse Ver., nov. 



Mteandriform corals that have distinct caliciual centers and radiat- 

 ing septa. (See p. 65.)

If we consider M. areolata (L.) as congeneric with Mceandra, as 

 above explained (p. 67), the name Manicina must either be dropped 

 altogether for a genus, or else applied to some other type. By the
