Peduncle The outline of the peduncle is very unlike that shown in Scammon's figure, instead of having the superior outline nearly straight, it has a short de- descent anterior to the flexures. It is as follows. From the posterior edge of the dorsal there is a gradual slope downward to a point opposite the penis - then there is a gradual rise until at a point midway between the flexures insertion of the arms, the curve reaches its greatest height; here the peduncle is deepest. From this joint, the slope to the flexures is gradual, not abrupt as in Scam- mon's figure. The lower outline of the body is as follows: - From the tip of the lower jaw to the penis the outline of the breast belly is a regularly convex line but not as strongly convex on the throat as it is shown in Scammon's figure. There is a sharp dip between the penis and the arms; the peduncle swells out a little directly behind this, then slopes gradually to flexures. The point of greatest swelling of the lower edge is a little anterior to [illegible] the greatest
