This small species, ol wliioli there is a sin.ii'le specinu'ii in 

 the collection of the llisho]) Mii>euni, was taken 1)\' the writer 

 from anionic" dead coral on W'aikiki reef. Ilonohilu. in i<j2i. 



It is ap])arentl_\- -omewhat closel}- allied to StiiiilUi iniilfi- 

 tubcrculata of llorradaile,'-' hut differs from that species in the 

 form of the roslrtini, and in the ornamentation of the sixth and 

 seventh ahdominal segments. 



'Idle s])ecies nnder consideration may easily l)e recoi^nized 1)_\' 

 the ornamentation of the sixth and seventh sei^ments of the 

 abdomen. The simiose character of the carinae has sui^i^ested 

 the specific name by which this species mav be desig^nated. 



On the sixth abdominal segment the carinae may be reco;.^- 

 nized as median, submedian, intermediate, lateral, and marsiinal, 

 all of which, except the median, unite with a transverse carina 

 extending- aktng the posterior border of the segment. The 

 medial carina is broken into two sections and does not reach 

 the transverse carina mentioned atove. The submedian and 

 intermediate carinae of this segment are curved and the lateral 

 with the marginal enclose an oval area on either side. A short, 

 blunt elevation is located on either side near the posterior border 

 between the submedian and intermediate carinae. By referring 

 to hgure 2, it will be observed that there is an approach to 

 symmetry in the arrang-ement of the carinae on the right and 

 left sides of the sixth seg'ment. 



The telson is also ornamented by numerous carinae, a few 

 of which are straight wdiile others are sinuose and scroll-like. 

 In addition to these, bhmt tubercles are interspersed with the 

 carinae especially near th.e ])osterior border. There is a linear, 

 median carina and immediatel\' on either side there is some 

 appearance of symmetrical arrangement among the carinae. but 

 it is not maintained on the remaining surface of the telson. 



Each nropod consists of a large subtriangular liasal segment 

 which has a lateral and a medial tooth produced from the pos- 

 terior border. The distal segment of the expodite is elongated,
