Length of body, eight lines (a female with eggs). The beak has a 

 minute point below at tip, seen with a high magnifier, and also two 

 minute hairs directed upward, as shown in figure Ji. The breadth 

 of the triangular beak is about twice its length, and its length is not

 unarmed on inner margin, but has numerous short setae around it near 

 tip. The mandible has two stout teeth above, with a more slender 

 one, and a cutting edge on a little lower level, precisely as in Crangon. 

 The base of the outer antennas is nearly as long as the basal scale.
