IgI2.] J. STEPHENSON: The Fauna of Yunnan. 277 
In one specimen a pair of small papille, each with a darker 
centre, was present on the posterior part of segment vii, nearly in 
the groove 7/,, and slightly median to the position of the sperma- 
thecal apertures. 
‘he sete formed an unbroken ring; they were slightly closer 
together ventrally than dorsally ; those of segments iii—vili were 
enlarged. ‘The following numbers were counted :—*/ix, “/xi, ”/xii, 
4] xix, a | xxvii. 
INTERNAL ANATOMY.—Sepia °/, and %/, moderately thick, '/, 
considerably thickened, */, and */,, absent, !°/,,—'/,, somewhat 
thickened. 
Intestinal diverticula small, conical, originating in segment 
XXvii; in one specimen there were one (right side) or four (left) 
small rounded secondary diverticula on the ventral border of the 
primary diverticula. 
Small testicular sacs, completely separated, in x and x1; 
vesicule seminales, irregularly lobulated in xi and xil. 
Prostates large, in six segments (xvii—xxii), divided up into 
a corresponding number of lobes by the septa. A thick yellow 
duct, with an S-shaped curve, rises from the middle portion of 
the gland in segment xix, the vas deferens joins the gland anterior 
to, but near, the origin of the prostatic duct. 
Accessory prostates correspond in position to the genital spots 
on segment xviii. 
The spervmathece are three pairs; the ampulla is ovoid in 
shape, narrowing gently to the duct, which is of considerable 
length, three-quarters as long as the ampulla. The diverticulum 
is often coiled; it is a narrow tube which when uncoiled equals 
the ampulla in length in some cases, while in others it is only two- 
thirds or one-half as long. 
An accessory gland was present on each side in the specimen 
which possessed the papillze posteriorly on segment vii; the glands 
corresponded in position with these papille, and were sessile on 
the inner face of the body-wall. 
Remarks.—Writing of Beddard’s inclusion of P. barbadensis 
with P. hawayana Michaelsentisays:—‘‘I am not yet quite con- 
vinced that this view is correct. Till now I have not seen a 
specimen—and I have examined many—which aroused any doubt 
as to whether it should be placed in the typical form or in the sub- 
sp. barbadensis. In the generally more robust typical form with 
stronger setz in the anterior part of the body the papillae near the 
male pores are always united at each side, occupying an oblong 
oval area medial from the male pores and mostly somewhat 
oblique. In the subsp. barbadensis the papille near the male 
pores are scattered, partly very near the male pores, partly near 
the median ventral line.’’ 
In the present specimens the dark spots near the male 
apertures had as a rule the character of slight depressions rather 
than of papillae; they were not confluent, and in this respect 
resembled the papille of the subsp. barbadensts rather than those
