COLLECTIONS FROM MELANESIA. 



must be referred to the variety cheverti, not only are the hepatic 

 granules entirely absent, but also the front has not the faintest 

 trace of trilobation. 



97. Leucosia craniolaris, var. laevimana. (Plate XXVI. fig. A.) 



I propose thus to designate, at least provisionally, a female speci- 

 men obtained in 10 fms. at Friday Island, Torres Straits (No. 153), 

 which is distinguished from the very numerous examples of 

 L. craniolaris in the Museum collection by the absence of a series 

 of granules on the inner margin of the palms of the chelipedes. 

 The carapace is narrower than is usual in L. craniolaris, very 

 polished and shining, and has two white spots on either side of the 

 The notch in the anterior margin of the thoracic 



gastric region. 



sinus is less distinct than is usual in L. craniolaris. A second 

 specimen from Torres Straits, in the Museum collection, resembles 

 Dr. Coppinger's example in its narrow rhomboidal carapace, but the 

 inner margins of the chelipedes are distinctly granulated. 



Specimens of Leucosia craniolaris are in the British Museum from 

 Tranquebar(07(Z Collection); Ceylon (E. W. II. Holdsworth) ; Penang 

 (Dr. Cantor) : Borneo and Chinese seas (coll. H.M.S. ' Samarang'); 

 Formosa (Matthew Dickson) ; Hong-Kong (Dr. W. A. Harland and 

 W. Stimjjson). 



98. Myra carinata, Bell. 



Flinders, Clairmont, N.E. Australia. A fine male dredged in 

 11 fms. (No. 108) seems to be referable to this species, which has 

 been recorded by Mr. Haswell * from Cape Grenville. 



Specimens are in the British-Museum collection from the Celebes, 

 Macassar (coll. Dr. Bleel-er), Philippines (Cuming), and Hong- 

 Kong (Dr. W. A. Harland). 



These differ slightly among themselves in certain points, as e. g. 

 the relative narrowness of the carapace, prominence of the inner 

 and upper orbital angles, and length of the posterior spines, charac- 

 ters that may be of some importance ; but large series are needed to 

 determine with certainty the distinctions between the very variable 

 species of this genus. 



99. Myra affinis, Bell. 



Four specimens are referred here from Port Denison, 4 fms. (Nos. 

 Ill, 122), first collection, and a larger female from Thursday Island, 

 3-4 fms., second collection (No. 177), which, like the examples men- 

 tioned by Mr. Haswell from Cape Grenville and New South AVales, 

 have a more or less distinct median longitudinal carina on the 

 carapace. 



Of M. ajjinis there are specimens in the British-Museum collec- 

 tion from the Philippine Islands, Masbate, Zebu (Cuming), and from 

 the Eastern seas (11. M.S. ' Samarang') without special locality.
