4 Dr. yi. Schultze on the Terrestrial Planarise. 



mouth is situated. It likes to bend the head upwards. At the 

 point of curvature on each side there is a closely packed group 

 of eye-spots, which are continued in an irregular series to the 

 posterior extremity. The anterior margin of the head appears to 

 be destitute of eyes. Length 1^ inch; breadth li line. Abun- 

 dant. 



"2. Geoplana octostriata. Habit and eyes as in the preceding 

 species ; colour pale yellow ; belly whitish ; on each side of the 

 back four dark brown, approximated, longitudinal streaks, far 

 broader than the longitudinal lines of the preceding. Not 

 rare. 



" 3. Geoplana elegans. Habit similar, but a little less attenu- 

 ated in front. Length 2~ in., with a breadth of 1 line. Eye- 

 spots very small, forming a rather broad dense band anteriorly, 

 becoming narrower and less dense posteriorly, and passing into 

 a simple row. Colou.r yellow; belly paler ; on the middle of the 

 back a broad, deep black, longitudinal stripe, and between this 

 and the lateral margin on each side a narrow, deep orange- 

 coloured longitudinal stripe. Only found once. 



" 4. Geoplana pallida. Of a similar form to the preceding. 

 Colour yellowish-white, with a single narrow, blackish, longitu- 

 dinal stripe on the back. Several specimens between boards. 



" 5. Geoplana atra. Deep black, beneath grey ; nearly cylin- 

 drical, but little attenuated before and behind. The eyes diffi- 

 cult of detection, although present. Proboscis more cylindrical 

 than in the freshwater Planaria, but always much wider at the 

 buccal than at the oesophageal extremity. Length 9 lines ; 

 breadth i a line. Found once under the bark of a rotten Figueira 

 [Ficus doliaria ?). 



*'6. Geoplana marginal a. Back and belly deep blackish-brown, 

 shining, with narrow, golden-yellow, longitudinal bands on the 

 middle of the back, and broader dull yellow bands along the 

 lateral margins; in the latter the eye-spots are very distinctly 

 visible, closely approximated in front, posteriorly in a simple 

 loose series. The animal, which was 3-4 inches in length, and 

 some lines broad, much attenuated before and behind, was 

 creeping in the house. 



" 7. Geoplana rufiventris. Back dark brown; belly tile-red; 

 moderately attenuated before and l)ehind. The ej'es closely 

 grouped in several rows, distinct on the margins of the anterior 

 part of the body, not detected posteriorly. The animal, which 

 was a few lines in breadth, and several inches long, was found 

 on wood. 



" 8. Geoplana olivacea. Belly yellowish-grey ; back greenish- 

 brown with dark brown longitudinal bands margined with paler 

 colour, darker towards the mai'gins, paler towards the head.
