MAKINE ISOPODS FEOM THE PHILIPPINE ISLANDS. 



head is produced in "two small nostril-like prominences in the center; a lower frontal 

 margin is adorned with ten teeth or turrets, divided into two sets of five, and exhibiting 

 between them a still lower frontal plate with two shining lobes." Baker « says, 

 "There are five teeth on the anterior border of the first peduncular joint of the anten- 

 nule, with a sixth smaller outermost," and "the epistome has two projecting teeth 

 transversely placed on the anterior portion." Whitelegge & says, "First antennae with 

 the basal joint stout, about three times as long as broad, without the marginal 

 denticles." 



The male of Cymodoce multidens has two or three teeth on either side of the post- 

 lateral margin of the terminal abdominal segment. These are not shown in Stebbing's 

 figure of Cymodoce tuberculosa, nor in Baker's figure, neither are they mentioned in the 

 descriptions of these authors. Whitelegge, however, says, "laterally, the sides are 

 convex, and ornamented with two clusters of small tubercles, those situated distally 

 are seated on a slight, oblique ridge." 



The flagellum of the first antennae is composed of seven articles in C. multidens. 

 Neither Stebbing nor Baker give the number of articles for the flagellum of either the 

 first or second antennae of C. tuberculosa. Whitelegge & gives fourteen for the first 

 antennae and nineteen for the second pair. The second pair in C. multidens have a 

 flagellum of ten articles. The epistome has two long projecting teeth, one on either 

 side of the median line. 



The body of the female is smooth, with the posterior margin of the terminal seg- 

 ment rounded, with only a slight indication of the median excavation with its central 

 lobe or tooth. The first article of the peduncle of the first antennae is not furnished 

 with teeth in the female as it is in the male. 



A number of specimens of this species, about forty, males and females, were collected 

 at station 5141 (type locality), Jolo Light, S. 17°"e., 5.50 mi. (6° 09' 00" N., 120° 

 58' 00" E.), at a depth of 29 fathoms, in coral and sand, on the surface of a sepia- 

 brown sponge. One male was taken at station 5145, Jolo Light, S. 16° E., 0.85 mi. 

 (6° 04 / 30 // N., 120° 59' 30" E.), at a depth of 23 fathoms, in coral and sand and 

 shells. 



The type is in the United States National Museum, catalogue number 40918. 



The species described by Whitelegge c as Cymodoce inornata is very similar to the 

 female of Cymodoce tuberculosa Stebbing. Whitelegge had but one specimen and 

 that was a female.

The tubercles on the surface of the body are more prominent than in the specimens 

 from Japan.
