dimidiatus, Th. ; 3, A. Jteius, Th., 1891-92. Sumatm. 

 — These three species do not possess the calamistruni and 

 cribellum characteristic of Acanilwctenus spinigerus, Keys, 

 (type), according to Thorell. Thorell has more recently 

 withdrawn liis species and placed them under the name 

 Acantheis. In Hist. Nat. Ar. i. p. 229, note, Simon refers 

 them to the subfam. Cteninffi in the fam. Clubionida^. 

 Of their tarsal claws Thorell says " Unguicnli tarsorum 

 bini graciles, longi, fortissime et aqualiter curvati." 



1891-2. Acantheis, Thor. Sv. Ak. Handl. xxiv. (2) p. 61, 

 note, is the name given by Thorell to include Acantho- 

 ctenns vari'atus, dimidiatns, and Icetus, from Sumatra. 

 Not having seen the types, I am unable to judge of their 

 affinities ; but, from Thorell's description, one would gather 

 that they belong to the two-clawed " Ctenins." On p. 61 

 he says " Ad species illas asiaticas recipiendas, quas ad 

 Acanthoctenum retuli et qute organis illis carent, novum 

 Cteninarum genus est creandum, quod Acantheis vocari 

 potest."

1891-2. Nydia, Thor. Rag. Mai. iv. vol. ii. p. 130. Type 

 N. punctata, Th., $ juv. Sumatra; received from Rev. 

 O. P. Cambridge {Forbes). — It appears probable that this 

 species, too, belongs to the Cteninw. Thorell says that 

 the eyes are in three rows, central row strongly recurved. 

 Ocular quadrangle half as broad again beiiind as in front 

 and a little longer than its anterior breadth. Labium 

 transverse, truncate at apex. " Tarsi unguiculis binis 

 muniti."

1878. jEnigma anstraliana, Karsch. S, 11 mm. Z. ges. 

 Naturw. (3) iii. p. 825. Type of genus. New South 

 Wales. — Karsch says that the eyes are in two rows, the 

 anterior somewhat shorter. He considers it to be near 

 Dolomedes and Ocyale, adding " aber es fehlt die After- 

 kiaue des Tarsus der Beine." One cannot judge well 

 from the description of its systematic position ; but i should 

 expect to find it somewhere near Zora.
