Hylo. 



373, f. 144, a fine exhibition of what patient search in the Coal 

 Measures may produce, in the way of an almost complete 

 restoration of one of the little insect-feeding lizards which 

 lived on the trees of the swamps. {Holonomus means forest 

 dweller.) Lyell found the first fragments inside a decayed 

 stump (turned to stone and standing in the cliflf of the Joggins 

 on the Bay of Funda; Dawson found others afterwards 

 in other tree stumps {calamites) \ skull, 1 inch long; whole 

 animal, probably six or seven inches long; vertebras, like long 

 hour-glasses; skin covering, bony scales ; bones, so imperfectly 

 ossified and yet so perfectly shaped as to suggest the suspicion 

 that we are dealing with the young of some larger lizards. —

f. 146. Found by Prof. Wyman in LyelPs specimons from the 

 Joggins' section of Coal Measures ; a slender lizard, 4 or 5 

 inches long ; possibly the young of IlyL aciedentatus^ but not 

 of Hyl. lyelli ; feeding on insects and grubs, in the coal 

 swamps, and itself eaten by the larger reptiles ; for, ''quantities 

 of its tiny bones occur in coprolitic masses [fossil dung] prob- 

 ably attributed to Dendrerpeton?^ Dawson. — XIII?

Hymenophyllites capillaris. Lesq. Geol. Pa. Vol. 2, p. 863, 

 plate 9, fig.6, looks like a Sphenophyllum branch, 

 but is a true Hymenophyllites in nervation and 

 outline. Perhaps only a variety of H. Hildreti^ 

 with which it was found at the Salines of the 

 Kenawha river, W. Va., in the lowest coal leds
