CETTSTACBA. 203 



type of their description is ia thfe collection of the British Museum, 



and is of very small size (length 6 lines, 12| mUlim.) ; surface of the 



carapace nearly smooth, with the regions little prominent and but 



slightly granulated ; a spine on the gastric and cardiac regions and 



a somewhat obscure ridge on the branchial regions ; teeth of the 



antero-lateral margins nearly confluent, postero-lateral spines with 



scarcely any traces of lateral teeth &c. Very similar characters are 



exhibited by the small specimen from Port MoUe (No. 93). In the 



smaller male from Thursday Island (No. 177) and in two specimens 



from the Australian seas, the largest of which measures about . 



10 lines (21 millim.), and which were-dredged by Mr. MacgiUivray 



• during the voyage of H.M.S. ' Eattlesnake,' in 7 fms. between Percy 



Island and the mainland, in lat. 21° 50' S., long. 150° 20' E., there 



is a considerable approach to the larger specimens from Thursday 



Island : in all the spines of the gastric and branchial regions are 



nearly obsolete ; but in two specimens the carapace is nearly smqoth, 



in the others it is granulated nearly as in the large specimen from 



Dr. Coppinger's cdllectiou, the spines of the postero-lateral angles 



are less prominent and less distinctly laciniated than in that example, 



though bearing distinct traces of lateral teeth. 



I have entered thus fully into the distinctions observable between 

 these specimens, because of the great degree of variability that exists 

 in many species of Parthenopidse; no one, I think, comparing two 

 specimens at opposite ends of the series would regard them as be- 

 longing to one and the same species. 



29. Cryptopodia fornicata {Fair.). 



Port Curlis, 11 fms. (No. 87), a female, first collection ; Thurs- 

 day Island (No. 175), second collection, a young male. Specimens 

 are in the British-Museum collection of this common species from the 

 'hx6.\3.nO(iesLrL{OeneralHardwieke) ; Borneo (from the India-Museum 

 collection) ; Philippine Islands, Mindoro {Oumiwj) ; Japan (Jamr- 

 rack) ; Lizard Island (J. MacgiUivray); and Moreton Bay ( Warwick). 

 Additional Australian localities mentioned by Mr. Haswell are Brook 

 Island, Cape Grenville, and Port Denison. 



It was collected in the Chinese seas during the voyage of H.M.S. 

 ' Samarang.' 



A very small male from Thursday Island (No. 165) has the cara- 

 pace and under surface of the chelipedes smooth, the gastric de- 

 pression shallow, and scarcely any trace of the oblique ridges on 

 the branchial regions usually characteristic of C. fornicata. 



30. Crjrptopodia spatulifrons, Miers. 



An adult male was received with Dr. Coppinger's second collec- 

 tion from' Thursday Island, 3-4 fms. (No. 175), and a smaUer male 

 from Prince of "Wales Channel, 7 fms. (No. 169). 



The larger example has the carapace more distinctly and coarsely 

 pitted than the typical specimen in the Museum collection from
