摘要: The mystacocarid crustacean Derocheilocaris typica has two microvillar organs, one new, the other previously unappreciated in literature. first is situated on head-shield and consists of three pairs cells: with microvilli a ballooned nucleus; smaller without special features; third large investing extending down to foregut. We call this new organ "cephalic organ" discuss value concept "dorsal organ", which it might have been included. second about 21 cells that cover proximal part dorsal surface labrum. are alike, being characterized by an apical field residual body. This here called "labral organ". Both organs neither sensory nor secretory do not qualify for membership any recognized systems. unable deduce their functions.
