The following specimens may be provisionally referred to F. headnelli, for, in the absence of 
associated series of bones, especially of upper and lower jaws, it is im])ossible in many cases to 
be certain of the specific determination. Since, however, many of these specimens have been 
found in the immediate neighbourhood of mandibles similar to that u])on which F. u-intoni has 
been founded (see below, p. 15G), and since that species appears to have been the commonest in 
the.se beds, some at least will no doubt eventually be referred to it. 
M. 8464. iSkull, wanting jmrt of the supraoccipital and most of the facial regions ; the cheek-teeth
