The anterior corners of the head are produced into sharp, 
curved projections. The rostrum is acute. The flagellum of

joints of the peduncle of the second pair are produced into 
a slender, acute process at the outer corner. The anterior 
corners of the first pereional segment are produced forwards, 
acute. The metacarpus of the first pair of pereiopoda is broad, 
armed at the anterior margins with a strong, tooth-like pro-
