posterior ventral surface is not excised. It is very common. Its length 

 is abont 



Family XIV. Euchlanidse. 



29. EucHLANis MACKUBA, Ehrenberg. 

 Not uncommon. It may be wortli noting that one specimen was ob- 

 served with well deSned setse on the foot. A few minutes afterwards it 

 was seen and the setaa had gone, though there had been no disturbance 

 of the slide or cover glass to account for this loss. If broken off they 

 must have been broken by the creature itself as it swam about ; it had 

 plenty of water to swim in. 



Family XV. Cathypnidse. 



30. Oatutpna LUNA, Ehrenberg. 



Very common. 



81. MoNOSTTLA CORNUTA, Ehrenberg. 

 A very small specimen seen, total length only -rro"- 



32. MoKOSTYLA QUADEIDENTATA, Ehrenberg. 

 Not very common. 



I obtained some specimens from the Museum tank on December 

 23rd, 1888 closely resembling this species, especially in having the typical 

 horns. They differed, however, in the following points ; the mallei were 

 not shouldered, nor was the outline of the claws wavy, the horns also 

 were straight, not curved. In a specimen killed with osmic acid the 

 points of the dorsal and ventral jalates were very distinct and were 

 joined by a membrane. Length of lorica uJo", total length a-^". 



33. MoNOSTYLA BULLA, Gosse. 



Not common. 



Family XVI. OoluridSB. 



34. COLURUS CAUDATUS, Ehrenberg. 

 The only specimen seen was much larger than the British species 

 apparently is. It was, too, rather longer in proportion to its breadth. 



35. Metopidia lepadella, Ehrenberg. 

 Only a few specimens seen ; the one drawn by me was only riio" 

 long.
