the margin itself. The rib, which arches across the front 

 of the ovicell, is composed of the two lateral spines. 



This is a very attractive species. Fabricius, in his 

 enthusiasm, could say of it, "Pulcherrima et perfectissima 

 haec omnium visarum." There are certainly few that 

 surpass it in beauty. 



L. puncturata, S. Wood, of the Red Crag, is a nearly 

 allied species, having much closer affinity with C. annulata 

 than with C. punctata, with which Busk compares it.

Zooecia ovate, large, sometimes pointed below, the upper 

 portion of the front surface occupied by a raised oval 

 area crossed by five or six ridges, which terminate at 

 each side of the area in prominent papillae, usually per- 

 forated at the apex, the furrows between the ridges 

 minutely punctured ; walls of the cell beyond the area 

 smooth and shining ; orifice subquadrangular, margin 

 straight above, slightly curved and projecting below, 

 unarmed. Avicularia of large size, elongate, with the 

 mandible enlarged and rounded at the upper extremity, 

 distributed over the colony amongst the zocecia. Ooecia 

 globose, smooth, closely united to the cell above, with a 

 keel down the front, terminating above in a knob, and 

 a pyriform fossa on each side. 



Var. a (fissa) . The furrows punctured towards the centre 

 of the area, and towards the edge of it traversed by a 

 fissure ; area small, not lobed round the margin. 



Colonies forming large, irregularly spreading crusts; the
