166 ANNALS OF SCOTTISH NATURAL HISTORY 



PLATE III. 

 PHILODINA HEXODONTA, Bergendal. 



As I am not aware that any figure of this species has 

 been published, and as the examples recently found in 

 Britain present several peculiarities which I have not seen 

 referred to in any notice of the species, I think it is desirable 

 to figure and describe the form which occurs here. 



Specific characters. Of moderate size, -^ inch when ex- 

 tended creeping. Formula 5-5 in all the examples studied. 

 Column constricted below. Antenna long, slender. Eyes 

 crimson, very close together, space between just equal to 

 diameter of eye. Stomach with pellets as in many Callidinae. 

 Foot short, spurs swollen at base, acuminate, acute, curved 

 outwards and downwards. 



Habitat. In bog-pools; first example among Sphagnum, 

 Blantyre Moor ; then several among Hypnuni fluitans from 

 the summit of Nutberry Hill. 



CALLIDINA ORNATA, . sp. 



Specific characters. Small, -gL inch extended, plicate. 

 Formula 3-3, rami with broad yellowish wing, which is 

 scalloped. Antenna long, tactile, with long setae. Foot 

 short, spurs broad at base, acuminate, acute, with short 

 straight interstice. 



Habitat. Among Sphagnum, Blantyre Moor. 



The only example studied was very sluggish in its 

 motions. Though kept alive for some days the corona was 

 never seen extended. 



ROTIFER QUADRIOCULATUS, . sp. 



Specific characters. Rather small, -^ inch extended. 

 Corona small, considerably narrower than trunk. Trunk 

 widest about or below the middle. Foot short for the 

 genus, spurs small, stout, incurved. Stomach yellow. Eyes 

 4, with many small dots between, the lower pair farther 

 apart than the upper. Formula 2-2. 



Habitat. Among Sphagnum, Blantyre Moor.
