Museum of Leyden by tliat of Gottingen, with specimens of 

 the common iSquiUa nepa. As these two forms have been 

 united by Mr. Miers, I may remark that in Squilla Icevis, 

 Hess, the rostral plate bears a median keel, that the lateral 

 processes of the second and third thoracic segments are unilobate 

 (and not bilobate as those of Squilla nepa), and that the postero- 

 lateral angles of the carapace are not simply rounded, as in 

 Sqioilla nepa, but project into a rather prominent lobe. 



Squilla nepa, Latr., represents the European Sq. mantis in the 

 seas of the Indo-Pacific region, having been recorded from the 

 Indian Ocean (Zanzibar, Ceylon, Madras, Singapore), Java, the 

 Philippines, Tahiti, and from the Chinese and Japanese seas. 

 According to Milne-Edwards this species ranges as far as the 

 coast of Chili. Miers mentions it as occurring on the eastern 

 coast of Queensland, Australia, having been found at Port 

 Curtis ; but I suppose that it is represented on the south- 

 eastern coast, namely, in the seas of Tasmania and New Zealand, 

 by the closely allied Squilla Icevis, Hess.

Eive specimens were collected in the Mergui Archipelago. 



Squilla rapliidea has been recorded from Zanzibar, Borneo, 

 and the Philippine Islands, and is distributed throughout the 

 whole Indian Ocean, the Malayan Archipelago, and the Japanese 

 seas. 



Genus Pseudosqitilla, Guerin. 



164. PsEunosQUiLLA pii/AENsis, n. sp. 



This interesting species was collected at Elphinstone Island. 

 It appears to be nearly allied to Pseudosquilla Cerisii, Eoux, a form 

 occurring in the Mediterranean, which constitutes, with the 

 American Pseudosquilla Lessonii, M.-Edw., the second section 

 of the genus Pseudosquilla in the ' Monograph of the Squillidae,' 

 published by Miers. This new form, which evidently represents 

 that section in the Indian seas, may be distinguished, however, 

 at first sight, from the two latter species by the dactyli of its
