Im. Very like T. latus, but Lain, at their ant. euds joined at the base 

 and above the join leaving only a thin line between them instead of a 

 considerable space as in T. latus. Dors, of Abd. irregularly reticulated by 

 raised rough ridges, reticulations large, spaces between slightly depressed, 

 granular. — Nph. Resembles that of T. latus, but the projections from the 

 edge of Dors, of Abd. and of each skin of the Dors, of Abd. different in form, 

 and each bears a transparent leaf-like scale with spinulated midrib instead of 

 a serrated spine. — Im. L. ca. 620 u.

2. T. dentatus Michael 1888 T. d., Michael, Brit, Orib., v. 2 p. 338 t. 26 f. 1—7,9. 



Im. Very like T. latus but differs in having Lam. with a blunt 

 point at ant. end bearing Lam. hair; post, to this outline concave but 

 rises to a large sharp point about the middle. Psstg. org. long, almost 

 filiform, distal end truncated. Dors, of Abd. (except border) reticulated, 

 reticulations large, rough, irregular, spaces between sunk and finely dotted. 



— Nph. Like that of T. latus but the brown projections round margin 

 of ".Dors, of Abd. are quadrifid, not trifid as in T. latus, the extra point being 

 at the insertion of the serrated spine, which spine is longer than in T. latus

 t. 26 f. 10. 



Im. Dark yellow-brown, very rough, pyriform. Cephth. long narrow: 

 Dorso-vertex reticulated. Lam. nearly straight, reticulated blades on edge, 

 smaller than those of T. latus, near together anteriorly. Psstg. org. almost 

 upright, with peduncles of moderate length, and large, shortly pyriform, rough 

 head. Whole edge of Dors, of Abd., except ant. margin, broken by strong, 

 rough projections bearing thick curved hairs. Dors, of Abd. not much 

 arched, edge slightly turned upward; no border, ornamentation similar 

 over whole Dors, of Abd. vizt irregular reticulations formed of very strong 

 rough ridges with deep granular pits between. — Nph. Of the type of 

 that of T. latus. but the projections round Dors, of Abd. and dorsal skins 

 mostly split into 3 bifid lobes and the large spines spinulated, not merely 

 serrated. — Im. L. ca. 590 |u.
