. Bulletin of the British Museum (Natural History), Geology. Fig. 16. Lates rhachirhinchus. First abdominal vertebra in : A. anterior, and B. left lateral views. (Paratype RG. ) frequently, some centra that are noticeably wider than deep ( about i| times, as compared with 1 to i\ times in the others). Whatever the characters of the central body, its exoccipital facets have a constant and characteristic form. They are confluent medially, with the zone of contact thrown upwards into a saddle-shaped area projecting well above the plane of the facets. Only in L. calcarifer and L. microlepis amongst extant species does one find a condition approaching that in L. rhachirhinchus. The first vertebra of L. rhachi- rhinchus, however, differs from that in all other Lates species in having a relativlye smaller facet area. As a result of this reduction in size, a vertical dropped from the posterior rim of the facet falls just behind the anterior face of the centrum and not,. 20 mm Fig. 17. Lates rhachirhinchus.
