MAKINE ISOPODS FROM THE PHILIPPINE ISLANDS. 



Meinertia angulata, sp. nov. 



Body oblong-ovate, 20.5 mm. long and 13.5 mm. wide. Surface smooth. Color, 

 bluish, marked with small yellow spots on the sides of the segments. 



Head triangular with the apex rounded, 2 mm. long: 2.5 mm. wide at the base. 

 Eyes almost vanishing; first pair of antennae, composed of seven articles, extend to the 

 posterior margin of the head. All the articles are flattened and somewhat dilated. 

 The second pair of antennas, composed of eight articles, are not longer than the first 

 pair; the last two articles are minute. 



The first segment of the thorax is produced on either side of the head in a rectan- 

 gular process. These processes extend but a short distance and give the segment 

 a rectangular appearance; they are concave, with the lateral margins upcurved. 

 This segment is a little wider anteriorly than posteriorly, being 6 mm. wide in the 

 region of the anterolateral processes and 5.5 mm. at its posterior 

 extremity. The first segment is 3 mm. long, the second and 

 fourth are each 2.5 mm. in length, the third is 2.75 mm., the 

 fifth is 2 mm., the sixth is 1.5 mm., and the seventh 0.75 mm. 

 long. All except the first are furnished with epimera which do 

 not reach the posterior extremities of the segments, but in the 

 first two extend beyond the anterolateral angles. 



The first five segments of the abdomen are short, the first 

 four being about 0.5 mm. each in length, the fifth being almost 

 1 mm. The first segment is narrow and is 



S deeply immersed in the thorax. The sixth or 

 terminal segment is wider than long, 3 mm.: 

 5 mm., and has the extremity bilobate, with a 

 slight emargination in the middle. The uro- 

 poda are not longer than the extremity of the 

 terminal abdominal segment. Both branches 

 are ovate and about equal in size and length. 

 Seventh leg. X7{. The legs are all prehensile, with a carina on 

 Fig. 21.— Meinertia angulata. X'2|. the basis of the last four pairs, which is 



extremely high on the last two. 

 Only one specimen was obtained, at Port San Pio, in a small stream near the mouth.

Genus RENOCILA Miers. 



Renocila ovata Miers. 



Renocila ovata Miers, Ann. Mag. Nat. Hist. (5), v, 1880, p. 464-465, pi. xv, fig. 11-14. Schioedte and 

 Meinert, Nat. Tidsskr. (3), xiv, 1883-84, p. 416-417. 



Locality: Bubuan Island, southwest side. Parasite on tail of snapper. 



One specimen, a male, agrees in every respect with Miers's description of this 

 species, except that the body is narrower and the posterolateral angles of the sixth 

 and seventh thoracic segments are more diverging. Miers's specimens were both 

 females. Schicedte and Meinerts's specimen from Amboina was also a female. 



* Genus CYMOTHOA Fabricius. 



Cymothoa stromatei Bleeker. 



Cymothoa stromatei Bleeker, Acta Soc. Scient. Indo-Neerland., n, 1857, p. 35-36, fig. 13. 

 Cymothoa eremita [Bruennich] Schicedte and Meinert, Nat. Tidsskr. (3), xiv, 1883-84, p. 259-266, 

 pi. vii, fig. 3-13. 



Cymothoa stromatei Lanchester, Proc. Zool. Soc. London, 1902, vol. 2, pt. 2, p. 377. 



Localities: Three females and four males were collected at Bubuan Island, Jolo. 

 One male was collected at Nogas Point, Panay.
