claws at least on legs i and ii are pectinate; legs iii and iv occasionally 

 have a clawlike empodium. The rostrum is short and broad. The che- 

 licerae are sickle-like, with two small setae on the dorsal surface of 

 the basal segment. The palpus is five-segmented, thick, strongly bent, 

 with a long tibial claw and weak setae. The palpal tarsus is almost 

 rudimentary with setae of various lengths. Peritremes opening at base 

 of chelicerae are present.

Discussion: Heteroteneriffia marina Hirst, 1926 was collected in 

 Malaya under rocks and stones on a rocky bank which was submerged 

 at half-tide every day and at full tide was under four to six feet of 

 water. At low tide there was a permanent pool of sea-water about 

 twenty feet wide between the bank and the shore. The mites moved 

 rapidly and were hard to catch. Other species and genera have been 

 described from such widely divergent localities as the Island of Ten- 

 eriffe, Paraguay, Egypt, and Australia. 



The structure of the mites indicates a predaceous habit.

Diagnosis: The pseudocheylids are colorless or reddish, small to medi- 

 um-sized mites from 0.23 to 1.1 mm. long. They are more or less elon- 

 gated and somewhat rhombic, with a strong furrow between the propo-
