DORA TODESMIDAE.

the first segment semi-elliptic, pointed and unilobate at the ends, 
scarcely concealing the head in front, as wide as the head or the other 
segments ; second segment with the carinae much enlarged, subfalcate, 
pointed below, not concealing the head or first segment ; segments 
dorsally very finely roughened, but with no tubercles or granules, 
the hairs numerous and long, but not dense. Carinae at the posterior 
corner apparently composed of two lobes, the first of which projects 
very slightly backward ; the outer does not project caudad, but is 
extended cephalad (!) into a strong, pointed, somewhat depressed 
process which, when the animal is coiled, fits into a socket in the de- 
ficient posterior corner of the preceding segment. Pores located on 
the outer lobe of the carinae, at the sinus between it and the basal 
lobe; pore formula 5, 7, 9, 10, 12, 13, 15-18. Last segment normal, 
rounded, without carinae or tubercles, the apex narrow, somewhat 
projecting and decurved. Legs short and slender, inserted rather 
close together. The type is Hynides7nus lanifer , sp. n., pale brownish 
in color, nearly 5 mm. long and .75 mm. wide, with 19 segments. It 
was collected at Goenceng Filoe, West Java, at an altitude of 8,000 ft. 
At fust I supposed this might have affinity with the another minute, 
hairy, Javan form described as Helodesmus, but the characters men- 
tioned seem to be the only points of resemblance. A relationship of 
Hynidesmus with Doratodesmus seems more probable, notwithstand- 
ing the great differences in form and size. An immature specimen 
from Tengger, East Java, (2.000 ft.) is apparently congeneric with 
the above ; it has 17 segments and measures 3 mm. by .4 mm. 
Family DORATODESMID^ Cook, 1896. 
Brandtia, p. 7. 
The typical and first described species came from Java. Three 
specimens now before me seem to belong to two species, both appa- 
rently distinct, at least in size and color, from D. armatus Poc. Both 
species have the supplementary margin regularly pectinate. 
* Doratodesmus muralis, sp. n. Carinae and segments covered with large 
flat areas which are light colored, whilephe space between them is dark ; 
dorsal processes yellowish, nearly smooth ; anterior subsegments light 
grayish, except a v-shaped black spot in the middle of the dorsum ; 
carinae composed of three lobes ; length about 12 mm., width 2.6 mm, ; 
two specimens from Western Java, at an altitude of 4,000 ft. 
Doratodesmus vestitus sp. n. The areas which cover the segments are 
large, prominent, and with a conic tubercle in the middle : posterior 
segments with three transverse rows of tubercles, while only two rows 
appear in D. muralis ; dorsal processes also tuberculate in the same 
manner as the segments ; the whole animal is covered with a dense 
bloom which becomes light yellow as the specimen dries ; in alcohol the 
color is uniform light brownish ; length about 14 mm., width 3 mm. ;
