narrow, almost equaliiii;- in length the proximal sej^'ment which 

 bears eleven cylindrical spinnles on its lateral border, the terminal 

 one of which is large and curved outward. The distal segment 

 of the endopodite is long and narrow. Two spinous processes 

 terminate the basal prolongation of the uroj^od, the inner one of 

 which is much the longer and reaches slightly beyond the middle 

 of the terminal segment of the endopodite. 



In this specimen lack of symmetry is seen not only in the 

 carinae of the telson but also in the dactyli of the raptorial limbs. 

 On the left dactylus there are four teeth on the inner border, be- 

 sides the terminal one ; on the right dactylus there are but three 

 teeth. The terminal one of the three teeth on the outer border of 

 the dactvlus is bifid when observed from a proxiiual or distal point 

 of view. 



In life the color of the animal is uniformly white with the 

 corneal area of the eye black. The specimen, preserved in alco- 

 hol, is yellowish-white with no change of color in the corneal 

 region of the eye. 



The total length from tij) of the rostrum to the extremity 

 of the submedian spines of the telson is 17 mm. Length of 

 carapace, including" rostrum, 3 mm. : of exi:K:)sed thoracic and 

 first five abdominal segments, ii^^ mm.; of sixth abdominal 

 segment and telson, 2'^ mm. 



There is no certainty that the individual described is mature. 

 It was kept under observation for more than a month during which 

 time it moulted once. No appreciable increase in size was ob- 

 served during this period. 



Type locality. W'aikiki reef, Honolulu, among dead coral. 

 Sex, female. Type specimen in Bishop Museum (Catalogue No.
