200 COLLECTIONS FBOM MELANESIA. 



In the second collection are two males and a female from Thursday 

 Island, 3-4 fms. (No. 175), and a small female obtained on the beach 

 at Port Darwin (No. 176). 



Nearly all of these specimens present the rostral characters 

 attributed by Haswell to his L. spinifer, but in one example of the 

 series the lateral teeth of the rostrum are absent. Traces of them, 

 as very obscure tubercles, exist in the typical examples of L. longi- 

 spinus in the British-Museum collection. 



In some of the specimens the spines of the cardiac and branchial 

 regions and of the posterior and postero-lateral margins are much 

 more strongly developed than in others. Besides the above men- 

 tioned Australian localities, Mr. Haswell records this species from 

 Darnley Island, and Cape Grenville. 



23. Lambrus lsevicarpus, Miers. 



Two small males are in Dr. Coppinger's second collection, obtained 

 in the Arafura Sea off the N.W. coast of Australia at a depth of 

 32-36 fms. (No. 160). They agree in all particulars with the 

 typical specimen, without definite locality, in the Museum collection. 



24. Lambrus longimanus (Linn.). 



To this species as I have defined it ('Annals', xix. p. 21, 1879) 

 are to be referred an adult male specimen from Flinders, Clairmont, 

 obtained at a depth of 11 fms. (No. 108) ; a male and a female from 

 Port Molle, 14 fms. (No. 93) ; and a female of large size, with ova, 

 from Fitzroy Island, 10 fms. (Xo. 113). 



This species, as I have already noted, ranges from the Mauritius 

 through the Indian and Malaysian seas to the North-eastern 

 coast of Australia. 



25. Lambrus nodosus (Jacquinot and Lucas). 



A small male in the first collection from Port Denison, 4 fms. 

 (No. 122), belongs here. Specimens from the same locality are 

 recorded by Mr. Haswell, the original types being from New Zealand. 

 In the second collection are a male and a female from Thursday 

 Island, 3-4 fms. (Nos. 175-177). 



Small specimens of this species have a considerable resemblance 

 to the L. intermedins, described by myself from the Corean seas*, 

 where also are perhaps to be referred small specimens from 

 Shark Bay, W. Australia (Bayner, H.M.S. 'Herald'), in the British- 

 Museum collection, from which L. nodosus is distinguished by the 

 prominent and globosely-rounded tubercles of the chelipedcs. In 

 L. intermedium the marginal tubercles of the chelipedes are flattened 

 and (in the typical specimen) the palms are quite smooth on 

 their upper surfaces. Ver) r small granules exist, however, on the
