202 Mr. J. W. Kirkby on some additional Species 



and perfectly smooth ; the leaflets from 2 to 3 inches long, and 

 an inch or more in breadth, rounded or slightly cordate at the 

 base, the lower ones in pairs supported on petiolules of 2 to 3 

 lines long, while the terminal one has a petiolule of an inch in 

 length ; and the terminal corymb expands almost into a panicle. 

 The combined fruit, after dehiscence, measures fully half an inch 

 across. In some respects the plant appears to approach Euodia 

 meliafolia, Benth.= Megabotrya meliafolia, Hance = Boymia gla- 

 brifolia, Champ., but differs widely in the character of the fruit, 

 in the crenulate margin of the leaflets, and in the pubescence of 

 their nerves, none of which characters are indicated in the several 

 descriptions of the plant of Southern China. A northern plant, 

 Phellodendron Amurense, Rupr. in ' Bull. Acad. St. Petersb/ and 

 in ' Maxim. Prim. Flor. Amur/ p. 73, t. 4, also bears consider- 

 able resemblance in its habit, in the size and composition of the 

 leaves, and in the form of the leaflets, but, if the fruit be cor- 

 rectly figured, is very different indeed."

XXI. — On some additional Species that are common to Carboni- 

 ferous and Permian Strata ; with Remarks on the Recurrency 

 of Carboniferous Species. By James W. Kirkby. 



[Plate IV.] 



In a former paper, where I noticed the occurrence of a Permian 

 Lingula in the Durham Coal-measures, a list was given of such 

 species as were then known to be common to the Carboniferous 

 and Permian life-groups*. Since the publication of that paper, 

 Mr. Davidson has shown that some additional Brachiopods may 

 be placed on the list of Carboniferous recurrents f ; and the 

 present communication is chiefly made for the sake of identify- 

 ing three forms of Entomostraca and Polyzoa belonging to the 

 Carboniferous series with species that have hitherto been con- 

 sidered exclusively Permian, and thus to still further increase 

 the list of these recurrent forms. 



The Carboniferous fossils were sent to me, along with others, 

 by Messrs. H. W. Crosskey and J. Young, of Glasgow, from the
