The very broad inner ramus of the uropods in addition to numerous setae carries nine 

 spines on the broadly rounded distal margin. The longer but very much narrower outer ramus 

 has a fringing of long setae with spines at intervals, the apex subacute. 



Colour, a pale ground sometimes strongly marbled with dark-brown stellate Hecks, some- 

 times carrying only more or less distant spots of brown. 



Length. A specimen here and there a little exceeded the length of 10 mm., but as a rule 

 specimens, even those loaded with young ones, did not reach fully 9 mm. Dana gives the 

 length of his species as nearly five lines, which may be reckoned as equivalent to 10 mm. 

 Schiodte and Meinert describe an ovigerous female of Dana's species, which was 6%5 mm. long. 

 Of their own species the ovigerous female described was 8"5 mm. in length, and the ' virgo ' 

 9 — 9-5. As they had two specimens of the latter form, it may be inferred that they differed 

 slightly in size. In their ' conspectus specierum ' these authors distinguish C. hirticauda as 

 having ' Cauda media obscure bisulcata vel subaequata ' and ' Oculi aequati vel subaequati ' 

 from 6'. hirsuta, with ' Cauda media manifesto bisulcata ' and ' Oculi manifesto granulati.' In 

 the present collection the bisulcation of the pleon is quite obscure, but whether the eyes are 

 less granular than in Schiodte and Meinert's specimens I have no means of determining. 



Locality. Minikoi, from rotten log in the lagoon, some of them marked as coming from 

 borings (possibly of Teredo) in the rotten wood. With them were some specimens of Limnoria. 



Gen. Lanocira, Hansen. 



Lanocim, 1890, Hansen, Vid. Selsk. Skr., Ser. G, Vol. v. Pt. 3, pp. 287, 313, 391, 395; 

 1893, Stebbing, History of Crustacea, p. 346. 



Hansen, having only a single species at command, notes that in this genus, as distinguished 

 from Alcirona, the hinder part of the body is naked, that is to say, not setigerous. But this 

 character is not applicable to the new species about to be described. 



.5. Lanocira gardineri, n. sp. Pi. LI A. 



The head (at least in the adult male) has the front upturned into a little horn, and near 

 the hind margin, adjacent to the rather large dark eyes, there are a pair of tubercles. The 

 appearance is therefore something like that of Excorallana tricornis (Hansen). The first segment 

 of the peraeon is considerably the longest, the seventh the shortest. The front side-plates are 

 rounded behind, the three hinder pairs somewhat quadrate and obliquely ridged. The first 

 segment of the pleon is medio-dorsally obsolete ; the fifth has its angles a little produced but 

 flanked by those of the fourth segment. The telsonic segment has the sides very slightly sinuous, 

 fringed with setae, and converging to a rather broad truncate ajiex carrjang jjluraose setae and 

 six spines. The dorsal surface of this segment is armed with twenty-six rather spine-like setae, 

 and there are a few on other parts of the back. 



The first antennae have the first and second joints coalescent, lying under the projecting 

 front of the head, the third joint a little shorter than the composite one, the six-jointed flagellum 

 shorter than the peduncle, and the whole appendage not longer than the peduncle of the second 

 antennae. This is robust, with the first three joints together equalling the stout but not very 

 elongate fourth, the fifth shorter and much narrower than the fourth. The flagellum, slightly 

 longer than the peduncle, has numerous setae on the firet seven of its thirteen joints.
