AUB No. 100402 (PL 1, fig. 2, PL 2, fig. 2). Material. In addition to the holotype, AUB No. 103838 (PL 2, fig. 1). Horizon and locality. Upper Senonian ; Sahel Alma, Lebanon. Description. Acid preparation has not been used on this species because there are only two specimens and material from Sahel Alma often gives poor results in transfer preparations. For this reason much of the cranial anatomy remains unknown at present. Measurements and proportions. The dimensions of the two specimens are as follows (in mm.), the first figure in each case being for the holotype, the second for 103838 : total length : 50-52, standard length : 40-c. 42, maximum depth of trunk : c. 20-18, length of head : 16-15, predorsal length : 21-23, preanal length : c. 28-27. Although both specimens are distorted, 103838 by oblique crushing, the holotype by displacement of the anal fin and deepening of the trunk, they are clearly closely comparable in size. G. stigmosus was a small, deep-bodied fish, about 40 mm. in standard length, with the maximum depth of the trunk about 46% of the standard length and the length of the head about 35% of the standard length. Neurocranium. The skull roof is not well exposed in either specimen. The supraoccipital crest was low, not projecting above the skull roof, and apparently. Fig. 4.
