6 Mr. E. J. Miers on the Squillidse. 



segments and the segments of the postabdomen are smooth ; 

 the three posterior thoracic segments similar to, but narrower 

 than the postabdominal segments. None of the segments bear 

 lateral spines. Terminal segment transverse, with a slight 

 median longitudinal elevation ; the posterior margin straight, 

 with a slight median emargination ; there are, on each side, 

 three postero-lateral marginal teeth, of which the two outer 

 only are acute. Eyes large. Antennules and antennas small 

 and slender ; the second, third, and fourth joints of the antenna? 

 bear each a small appendage on their inner or under sides ; 

 the basal antennal scale is large, lamellate, and ciliated. The 

 first maxillipedes are slender, elongated, and terminate in a 

 flattened, dilated, and ovate joint. The large raptorial limbs 

 (second maxillipedes) are very powerful and greatly elon- 

 gated; the penultimate joint or propus is very finely denticulated 

 and armed with four strong mobile spines near its base, and 

 the terminal joint (in the male) with nine or ten very strong 

 spines. The penultimate joint of the three following limbs is 

 considerably enlarged, produced and rounded posteriorly. The 

 appendage to the antepenultimate joint of the three posterior 

 thoracic limbs is styliform and slender in the adult. The rami 

 of the postabdominal appendages are foliaceous and very greatly 

 enlarged. The distal ends of the basal portions of the appen- 

 dages of the sixth segment are armed below with two exceed- 

 ingly strong spines and a single spine above ; and the rami are 

 ovate, the terminal joint of the inner being slightly the larger. 

 Length of the largest male upwards of 12 inches.

This, which is the largest and perhaps the most strikingly 

 coloured, is also one of the commonest and most widely dis- 

 tributed species of the genus. Specimens are in the British- 

 Museum collection from Rodriguez (H. H. Slater , Esq.), 

 Indian Ocean {Hits. Leach), Duke-of-York Island (Rev. G. 

 Brown), Philippine Islands (H. Cuming, Esq.), Fiji Islands 

 {II.M.S. < Herald'), Sandwich Islands (W. H. Pease, Esq.), 

 Samoa Islands (Rev. S. J. Whitmee), Eastern Seas (Madame 

 Ida Pfeiffer) * 



The only females I have seen are two collected by Mr. 

 Whitmee at the Samoa Islands ; and in the only one possessing 

 the large raptorial limbs, the spines arming the inner margin 

 of the dactyl, instead of being strong and elongated as in the 



* There is in the British Museum a fine male example of this species, 

 obtained from H.B.M. Consul Petherick, and stated to have come from 

 the "White Nile." It was, in all probability, obtained in the Red Sea, 

 as I am informed by Dr. J. Murie, who accompanied Consul Petherick, 

 that the latter gentleman took ship on his return at Suakin, on the Iied- 

 Sea coast.
