296 DR. J. G. DE MAN ON THE PODOPHTHALMOUS 
Museum of Leyden by that of Gottingen, with specimens of 
the common Squilla nepa. As these two forms have been 
united by Mr. Miers, I may remark that in Squilla levis, 
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 
Squilla 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 levis, Hess.

Five specimens were collected in the Mergui Archipelago. 
Squilla raphidea 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 PsEuDosQuILLA, Guérin. 
164. PsEUDOSQUILLA PILAENSIS, 0. sp. 
This interesting species was collected at Elphinstone Island. 
lt appears to be nearly allied to Pseudosquilla Cerisit, Roux, a form 
occurring in the Mediterranean, which constitutes, with the 
American Pseudosquilla Lessonit, M.-Edw., the second section 
of the genus Pseudosquilla in the ‘ Monograph of the Squillidex,’ 
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
