Ohs. Besides being far lai'ger than the specimen above 

 described, which I always thought to be more or less deformed, 

 this one probablj presents us with the typical characters of 

 Leiapia australis, and hence my object in appending the 

 above description. It must also, independently of its " typi- 

 cal " value, be considered a large calcareous sponge as the 

 latter generally run. The spiculation may be a trifle larger 

 than as above described, but the ridges are an entirely new 

 feature, which in their characters are alone sufficient to dis- 

 tinguish the species; while the large acerate spicules of the 

 body, arranged both transversely and longitudinally in the 

 wall, represent the large sagittal triradiates of the " inarticu- 

 late " calcareous sponge-structure ; the rest of the spicules 

 here, including that remarkable form, viz. the " fork-like tri- 

 radiate," to which I have above alluded as being so interesting 

 in connexion with the fossil species Sestrostomella^ being 

 dwarfed into comparative insignificance.

Fapilio Adamsoni. 



Upperside. Anterior wings brown-black, darker towards 

 the base, the nervures and rays between the nervures black. 

 Posterior wings the same colour as the base of the anterior 

 wings, paler towards the anterior margin, crossed beyond the 

 middle by an irregular band of five rosy-white spots, the 

 spot nearest the anterior margin cordate, the next three 

 conical and lunulated externally, the fifth spot at the anal 

 angle nearly obsolete ; below the band are three submarginal 

 large spots^ lunular, the innermost grey flushed with rosy 

 carmine, the middle spot grey, less rosy, the third the same 

 colour as the band. 



Underside. Anterior wings as above, but paler. Posterior 

 wings with the band brighter, larger, more regular and 

 curved, containing six spots, the spot on the anterior margin 

 nearly square, the second the largest and nearly divided by a
