The niK'lial uas very wide (about 230 mm.), wliile its 

 leiii'tli ill the niidiUe line was onlv about 67 nun. It seems 

 to have liad a small median ])rominence on either side, of 

 whieh its border is slif^htly concave. Its form is ))eculiar, 

 and I liave l)cen unable to find any other nucluil similar to it. 

 The neural bones are long and narrow. The first is four- 

 sided, the long lateral borders being slightly convex ; the 

 posterior end is bluntly pointed to fit into a notch in the 

 front border of the second. This latter, together with 

 the other neurals preserved, has a short anterior lateral 

 border and a long posterior one; the posterior end in all is 

 rounded and fits into a concave anterior border of the bone 

 behind. The anterior costal is roughly triangular in outline, 

 its outer border occupies exactly the length of the first two 

 mar-rinal bones. The second costal is about 70 mm. wide at 

 its inner end, biit widens out to about double this before it 

 joins the marginals. The third costal, on the other liand, 

 which is al)Out the same width at its inner end, narrows to 

 about half this at its outer end. The fouth costal widens 

 out like the second. The fiftb is only partly preserved. 

 This alternate widening and narrowintr of the costal bones is 

 seen in many species of Testudo, but liere the form of the 

 neurals and their relations to the costals is quite dilTerent. 



The grooves marking the outlines of the horny shield are 

 well marked. There may, perhaps, have been a very small 

 nuchal shield ; the first marginal shield, in correlation witli 

 the great width of the nuchal bone, is very long from side to 

 side and narrow. The form of the costal and marginal 

 shields and their relations to the underlying bones will ])e 

 best understood from the figure. 'The shape and arrangement 

 of the shields are much as in Eiittjs. 



This specimen has been compared with any other forms 

 with which relationship seemed likely, but differs very 

 considerably from all. Its chief distinguishing cliai-acter- 

 istics are the great width of the nuchal bone, the long narrow 

 neurals, and the alternate widening and narrowing the costals. 

 I propose to refer this specimen to a new genus, Pdianemya, 

 the specific name being Patanemi/s bartonensis, sp. n. It 

 seems to belong to the family Einydidie.
