Proboscis skeleton from a wax model, ventral side, x 33. it does not extend in front of the stomochord and stops in front of the blind-pouches, it is also much broader and its vessels are thicker in B. hydrocephalus than in B. studiosorum (fig. 49). The function of the glomerulus is not quite known. That it is an excretory organ is beyond doubt, but besides it may help in extending the proboscis by secreting water into the proboscis cavity. Its greater size in B. hydrocephalus would then be in correspondence with the size of the proboscis. In this species the two lateral halves of the glomerulus, although extending in front of the pericardium, are separated here.
