I have seen but one species of Thalassijkt, but possess 

 a drawing of another, which was given to me'bji'Gol. Hafd- 

 wicke, who informed me that it was designed by a native 

 of India, from a specimen which he gave to him for that 

 purpose.

I have figured this species to enable those naturalists 

 who have not seen the genus Thalassina to compare it 

 with Gehia *, with which it has lately been arranged by 

 Latreille in Cuvit-r's Regne Animale.
