the species was. For my own part, I cannot say that a Spirifera which could he 
definitely referred to the present species has ever come under my notice from Queens- 
land rochs. , , ^ ^

Sp. Char. Cardinal margin of dorsal valve long and straight ; area moderately 
large; alar angles rounded ; fold wide and prominent, hut not angular, rounded and 
plain, expanding rapidly towards the front, bounded on each side hy a marked depres- 
sion or groove. From twelve to fifteen simple, flattened, curved ribs ornament the 
lateral portions of the valve, and are crossed by laminte of growth, which are also con- 
spicuous on the fold. _ , • , , 4 . 
Ohs. This shell is only known to me in the condition of decorticated casts oi 
the dorsal valve, averaging in size from one to one and a-quarter inches long. e 
chief points of interest are the plain fold, and the simple, flattened riblets. It is a very 
interesting species, which I have, so far, been unable to determine but the general 
appearance of the specimens is well conveyed by the figure given by Mr. Etheridge, as 
above quoted. I have described the fold as plain, but on two of the specimen's before 
me there is a faint division perceptible, in others its surface is 
great amount of convexity could have existed in this valve. The pub '^^ec gure o 
not convey to me the idea of Spirifera striata at all, nor do I think it can be s 
referred, the riblets being much too wide for the size of the valve. 
The figure of De Koninck’s S. yuennamensis, published by D Orbigny, 
resembles the specimens from Eockhampton, only the former is much larger, and the 
ribs are less in number, only nine on each side; the comparison is, however worth 
entertaining. The sulcus on each side the fold is a marked feature, and should assis 
in identification. , • n i -o^n'k.

Ohs. Ill-preserved Spiriferse, probably referable to this species, have been 
with at two localities. Eespecting the specimen figured by Mr. Etheridge, he says 
“It has not the number of ribs described by Sowerby; but their angular, imbnc > 
or fimbriated condition, the width of the mesial fold or ridge, and the pointed bea , 
the transversely fusiform shape of the one valve, are sufficient to warrant my ^etai 
this name for the sjjccimen from Gympie.” He adds— “ Five or six rows of a 
• angular imbrications are distinguishable upon the mesial fold, and traceable a g 
attenuated lateral wings of the cardinal angles. — , 
‘Probably “Bowen River” is correct.
