A REVIEW OF THE MYSIDACEA 79 



fied by H. J. Hansen that was collected by the Albatross at latitude 

 1°45' N., longitude 137° W. 



Distribution. — This species is more oceanic in its habit than are S. 

 vulgaris and 8. affinis, as Hansen (1910) has already observed and as 

 the present records indicate. The species is widely distributed in the 

 tropical waters of the Pacific and Indian Oceans from the Arabian 

 Sea to China. 



Remarks. — From the fact that females bearing eggs or embryos in 

 the brood pouch occurred in April, August, and November it would 

 appear that this species breeds all the year around. 



SIRIELLA ANOMALA Hansen 



Siriella anomala Hansen, 1910, p. 41, pi. 5, figs. la-H.— Tattersall, 1936b, p. 146. 



Occurrence. — Pacific: The Albatross collected material at two 

 localities, without station numbers : Kusac, Caroline Islands, surface 

 tow net with electric light, February 7, 1900, 66 males, 35 females, 

 breeding ; Arno Atoll, Marshall Islands, surface tow net in the lagoon 

 with electric light, January 24-26, 1900, 3 males and 10 females, 

 breeding. Philippine Islands: The Albatross collected at one lo- 

 cality, without station number, Port Matalvi, Luzon, electric light, 

 surface, 7 :45 p. m., November 23, 1908, 6 males, 4 females, breeding. 



Distribution. — Known heretofore only from the waters of the East 

 Indian Archipelago (Hansen) and the Great Barrier Reef (Tatter- 

 sall), range here extended to the Caroline, Marshall, and Philippine 

 Islands. The breeding season of the species extends from November 

 to the beginning of February at least, since most of the females in this 

 material have either eggs or embryos in the brood pouch. It appears 

 to be a coastal form, abundant at the surface during hours of darkness. 



SIRIELLA DISTINGUENDA Hansen 



Siriella distinguenda Hansen, 1910, p. 42, pi. 5, figs. 2a-e. 



Occurrence. — Philippine Islands : The Albatross collected material 

 from Sablayan Bay, Mindoro, electric light, surface, 7 p. m., Decem- 

 ber 12, 1908, 1 male, 9 females. 



Distribution. — Known from the original record by Hansen from the 

 waters of the Dutch East Indies ; range here extended to the Philippine 

 Islands. 



SIRIELLA DUBIA Hansen 



Siriella dubia Hansen, 1910, p. 44, pi. 5, figs. 4a-e. — Tattebsall, 1922, p. 455, 

 figs. 5a-b ; 1936b, p. 146, fig. 1. 



Occurrence. — Philippine Islands : The Albatross collected material 

 from Nasugbu Bay Anchorage, Luzon, electric light, surface, 7 : 30 

 p. m., January 21, 1908, 1 immature male.
