and is now in blocks ready to be boxed.  Excavation has not yet proceeded far enough to ascertain whether of not the limb bones of this specimen are present, but they are all or nearly all present in the upper skeleton.  We think that the tail is complete to about the -- th joint.  It is   disarticulated here but it is not certain yet that the whip will not yet be recovered.  We cannot tell yet about the samller protion of the tail No. 355.  The skull and the greater portion of the neck are lost in the latter specimen.  If they were originally present they ahve been eroded away as the posterior cervicals extended to the weathered surface of the ledge.  The skull and two or three of the anteriror cervicals of No. 340 had been detached and were not in place.  There is a possiblility that this skull may be found before the two skeletons are removed but we have hardly expected it.  There is somewhere   500 feet of the rock of the bone layer yet to be remobed and there are always possiblities of uncovering a skull in this quarry.  There is also a great probability that the other valuable material will be found.  So far as I know there is only one case in which the skull in this quarry.  There is also a great probability that other valuable material will be found.  So far as I know there is only one case in which the skull of a Diplodocus has been found in undoubted association with the skeletonand that was in thsi quarry.  We have found several Diplodocus-like skulls both above and below the average size.  The big Dinosaurs seem especially pron to lose their head.  Perhaps they had not the brain enough to remember what they did with them.  Anyway a plaster skull can be obtained and, as these big fellows are not very pretty they look as well as could be expected with one of these.



 To sum up, from these two skeletons it seems that you can get a very nearly complete mount with the possbilbe exception of
