208 Occasional Papers Bernice P. Bishop Museum 
In 1894 Bigelow formed a new genus™ to include a number 
of species previously described under the generic term Gonodac- 
tylus and having the dactylus of the raptorial limb dilated at the 
hase and provided with lateral teeth. Gonodactylus hansenii, 
described by Pocock, is such a species. 
There are in the collection of the Bishop Museum three 
specimens, one male and two female, which correspond closely 
with Pocock’s description of the type 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 Odontodactylus scyllarus (Lannaeus). In the descrip- 
tion of the latter species, Miers!’ mentions the sixth abdominal 
segment as having eight ridges which usually terminate in spine- 
lets, with two smaller prominences near the base. In the speci- 
mens in the Bishop Museum but six of the carinae of the sixth 
abdominal segment terminate in spines, and Pocock’s figure seems 
to indicate a similar condition. 
Figure 1, e, is a drawing of the male accessory organ of the 
first abdominal ‘appendage of the same species. Figure 1, f, 
represents the details of the sixth abdominal segment and_ the 
telson of a Bishop Museum 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 four 
abdominal segments. There is a dark-brown patch on the basal 
half of each uropod. The eyes are dark brown and the’ flagella 
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.
