One specimen from an expedition in 1976 was also included for two of the mouthparts (mandible and labium), as these were badly positioned for drawings on the new slide from the Dana samples. They are however identical when examined. The new slides we produced showed no differences to the type-slide, but we managed to make better drawings from these new slides.
