In the Chiroteuthidae and Tracheloteuthidae (Figure 1), they form lamellae which also taper near the base of the gills (Plate XXXVI, Figures 1; 2; Plate XLII and XLIII, Figure 1).

The funnel cartilages, situated on the lateral posteroventral margin of the funnel, are of charac- teristic form in each family; they are fitted into the mantle cartilage and form a closure apparatus. The musculus collaris is inserted on the neck in a fiat, oblong cartilage the counterpart of which is the dor- sal mantle cartilage. In some genera (Symplectoteuthis, Grimalditeuthis), the funnel cartilages are so firmly fused that the mantle margin is connected with the funnel at two points. This is especially the case in the Cranchiidae, in which the two neck cartilages, too, are fused (Plate XLIX, Figure 3). mu. depr. inf. figure 1. Brachioleulhis riise/Steenstr.
