A label accompanying the specimens from Cataingan Bay reads: "Very ravenous, 

 attacking small fishes, first devouring eyes, then gills, then working into body cavity — 

 all of this is done inside of ten minutes." 



Dana's specimens were from the Sulu Sea, Hansen's from Nangkovry, Nicobar 

 Islands, Stebbing's from Conflict Group, New Guinea, and Isle of Pines.

 Locality: One specimen, a female, from Santa Cruz, Marinduque Island (electric 

 light); three specimens, two males and a female, from Tomindao Island anchorage 

 (electric light); thirteen specimens from Java Island anchorage (electric light); nc 

 locality, twenty specimens; three specimens from Sabayan Bay, Mindoro; one speci- 

 men from Port San Pio V, Camiguin Island. Stebbing's specimens were from Barawon,

Cirolana epimerias, sp. nov. 



Body ovate, 14 mm. long: 5.5 mm. wide. Surface smooth. Color, yellow. 



Head wider than long, 1.5 mm.: 2.5 mm. Eyes very small, composite, and situ- 

 ated in the anterolateral angles. Anterior margin of head widely rounded and without 

 any median point. There is a slight elevation on the pos- 

 terior margin in the median line. The first pair of antennae 

 have the first two articles short and subequal. The third 

 article is 1.5 times the length of the second. The flagel- 

 lum, composed of five articles, extends to the middle of 

 the fifth peduncular article of the second antenna?, or a 

 little beyond the anterolateral angle of the first thoracic 

 segment. The second antennae have the first two articles 

 short and subequal ; the third is about twice as long as the 

 second; the fourth and fifth are subequal and each is twice 

 as long as the third; the flagellum, composed of sixteen arti- 

 cles, extends to the posterior margin of the third thoracic 

 segment. The frontal lamina is short and broad, about twice 

 as long as wide. 



The first segment of the thorax is the longest, being 2 mm. 

 long; the five following segments are subequal, each being 

 1.5 mm.; the seventh segment is the shortest, being 1 mm. 

 long. All the segments, except the first, are provided with 

 epimera; those of the second and third segments do not reach 

 beyond the postlateral angles of the segments; those of the fig. 3.— Cirolana epimerias. 

 last four extend beyond the posterior margins of the seg- x 4 ' 



ments; those of the fifth, and especially the sixth, are greatly produced and extend 

 outward laterally in a most conspicuous way. 



The first abdominal segment is entirely concealed by the seventh thoracic segment; 

 the three following segments are very short, all three together measuring 1 mm.; the 

 fifth segment is long, being 1 mm.; the sixth or terminal segment is a little wider 

 than long, 2.5 mm.: 3 mm. It is triangular in shape, with sides converging to a 

 rounded extremity armed with six spines. The inner branch of the uropoda is large 

 and widely rounded posteriorly and extends beyond the extremity of the terminal 

 abdominal segment; the outer branch is narrower and shorter than the inner branch 

 and also posteriorly rounded. 



The posterior margins of the last two segments of the thorax and the first three 

 abdominal segments, the margins of the uropods, and the terminal abdominal seg- 

 ment are fringed with short thick hairs. 



The first three pairs of legs are short, the last four pairs elongate. All are furnished 

 with spines.
