Hob. — Dredged off St Monans in 1892, apparently not 

 very rare ; and again on 22nd May 1901, several specimens 

 were obtained. This form differs from the T. maleolata 

 described by Dr Brady in the structure of fifth pair of 

 thoracic feet, but is otherwise identical with it.

Rah. — This species was obtained somewhat sparingly in 

 material dredged off St Monans in 1896, and again in 1901. 

 It has a general resemblance to T. maleolata, but the furcal 

 joints are distinctly shorter.

Hab. — Dredged off St Monans in 1891, and again in 1901 ; 

 apparently rare. This species and the next are easily dis-

 pair of thoracic feet of the female.
