The tips of the four branches lie, in the figure, on a curved line which represents the margin of the anterior spiracular wall. The distinct bifurcation of the dorsal ends of the two spiracular cartilages is interesting owing to the fact that they show great resemblance to the branching hyal rays of the same stage. These latter rays are shown in Figure 4 where some of them are simple rods of cartilage while others have bifurcate posterior ends. Great similarity is to be observed on comparing the two spiracular cartilages with.
