111 T894 Dii^elow tornied ;i new i^enus'^ to include a number 

 of s])ecies previously described under the .generic term (jonodac- 

 tvlus and having' the dactylus of the raptorial limb dilated at the 

 ]:ase and ])rovided with lateral teeth. Gonodactyhis liansenii, 

 described by Pocock, is such a species. 



There are in the collection of the IHshop Alusetim three 

 specimens, one male and two female, which correspond closely 

 with P(Kock"s description of the ty])e specimen and apparently 

 belong" to this species. In Pocock's description it is said that 

 the sixth abdominal tergite and telson resemble the corresponding 

 segments in Odoiifodacfyliis scyllanis (Linnaeus). In the descrip- 

 tion of the latter species, Miers^' mentions the sixth abdominal 

 segment as having eight ridges wdiich usually terminate in spine- 

 lets, with two smaller prominences near the base. In the speci- 

 mens in the Bishop Musetim but six of the carinae of the sixth 

 abdominal segment terminate in spines, and Pocock's figure seems 

 to indicate a similar condition. 



Figure T, r, is a drawing of the male accessory organ of the 

 first abdominal appendage of the same species. Figure i. f. 

 represents the details of the sixth abdominal segment and the 

 telson of a Pishop ]\Iuseum specimen. 



The color of the Bishop Museum specimens, preserved in 

 alcohol, is uniformly light-yellowish above with a light-pink pos- 

 terior margin on each of the exposed thoracic and first fotir 

 abdominal segments. There is a dark-brown patch on the basal 

 half of each tiropod. The eyes are dark brown and the tiagella 

 of the antenna are pink. 



Pocock refers to the color of the type specimen as yellowish- 

 pink. 



The largest specimen in the Bishop Museum collection, a 

 female, measures 43 mm. from the tip of the rostrum to the 

 extremity of the submedian marginal spines of the telson. Ac- 

 cording to Pocock the type specimen measures 60 mm.
