 Haliporus Sp. Bate. 



The genus Haliporus Sp. Bate at present comprises not less than 23 species, inclusive 

 the two new ones that were captured by the "Siboga". The species of this genus are found 

 in various parts of the Atlantic, the Pacific and the Indian Oceans, but have not yet been 

 observed in the North Pacific, the Seas of Japan, along the east coast of Africa or in the 

 Red Sea. Two which are closely related, viz. Ha lip. iiiicrops (S. I. Smith) and Halip. laevis 

 Sp. Bate, occur both in the Atlantic and in the Indopacific. Halip. inicrops, indeed, occurs 

 in the western part of the North Atlantic, but has also been observed in the Arabian Sea 

 and in the Bay of Bengal; the other, Halip. laevis, was taken by the "Challenger" Southwest 

 of Sierra Leone and off Manila, Philippines. 



Of the other species, Halip. affinis occurs as well in the Sea of the Antilles as at the 

 Cape Verde Islands, and Halip. debilis (S. I. Smith) is found along the east coast of the 

 United States as far as the Antilles but also at the Azores and in the eastern Atlantic. Halip. 

 modestil s is confined to the east coast of the United States, Halip. robiistiis (S. I. Smith) and 

 Halip. tropicalis Bouv. are inhabitants of the Caribbean .Sea, the latter also of the Florida 

 Bank and Halip. Mul leri{S^.'Qa.lG.) has hitherto only been recorded from the sea off Montevideo. 

 Halip. androgynus Bouv. is known from the .Sea between the Senegal and the Cape Verde 

 I.slands. Four species occur along the west coast of Central America, viz. Halip. diomedeae 

 Fax., Doris Fax., Nerens Fax. and Tlictis F"ax., Halip. curvirostris Sp. Bate was observed by 

 the "Challenger" near the Low Archipelago and in the South Pacific and Halip. obliquirostris 

 Sp. Bate from off the Kermadec Islands, was taken by the "Siboga" at the Kei Islands. 



Two new species were discovered by the "Siboga", each in several localities far remote 

 from one another. Halip. aequalis Sp. Bate and Halip. neptunus Sp. Bate are not only 

 known from the Philippines and from other localities of the East Indian Archipelago, but also 

 from the Seas of India: Halip. aequalis, indeed, occurs also in the Andaman Sea, off Ceylon 

 and in the Arabian Sea, Halip. nepttiniis in the Bay of Bengal. Of four other species Halip. 

 taprobanensis A. And. occurs in the Gulf of Manar and oft' Cape Comorin, while Halip. villosus 

 Alc. & And. is still only known from the Arabian Sea, Halip. Liicasii (Sp. Bate) occurs in the 

 East Indian Archipelago, while Halip. i/ial/iacnsis Borr., finally, was dredged off Saya de Malha, 

 in the Western Indian Ocean. 



Halip. Mülleri is found in rather shallow water, between 7 and 44 fathoms and the 

 new Halip. propinqiiiis was captured at Stat. 89 at a depth of only i i m., but in two other 

 Stations also at depths of 538 m. and 835 m. Some other species are living in deeper water,
