Herbst gives a reference to Rumph's Squilla aremaria terresti 

 " Rumpli- AIus. tab- 3. fig- E-/' which ^lilne-Edwards cites 

 tab. 4, tig. li., vvniie Eabricius refers to " Cancer arenarius, 

 Rumph. Mus. tab. 3, fig. 2," and Bigelow quotes Rumph. 

 Amboin. Rarit., p. 6, 1705. Rumph in his Amboinsche 

 Rariteitkamer, p. 4, gives the alternative names Locusta or 

 SqaiLLa Arenaria Terrestris, and the species is represented 

 lull size on his plate 3, fig. E. Herbst adduces Cancer 

 arenarius, etc., from " Linn. Mus. Adolph. Frid., p. 86," a 

 work of 1754. Linnaeus himself in 1758 gives the same 

 reterence tor Cancer ma 7i^is, folio wed by a reference to "/^z/w///. 

 ■Mus. t. 3,y. is"., C. Arenarius." Since this habitat includes the 

 Asiatic, Indian, and Mediterranean Seas, the Linnean species 

 may be taken to cover Sqiiilla mantis as well as Lysiosqiiilla 

 maculata. The specific name which Herbst adopts with 

 proper respect to his Dutch predecessor has generally been 

 set aside as of later date than that given by Fabricius, but, 

 so far as can be known, they are contemporary, for although 

 Herbbt's second volume is dated 1796, the parts of it in 

 which Cancer [Ma?itis) arenarius was published belonged to 

 1793. in the conflict of claims the Fabrician name maybe 

 allowed a prescriptive preference. 



This large and striking species cannot be identified simply by 

 the transverse blue bands, since they are found also in Sqinlla 

 vittata, Milne-Edwards, which "Miers, following the lead of ^lilne- 

 villaia, Milne-Ldwards, which Miers, following the 

 lead of Milne-Edwards himself, identifies with the 

 earlier Squilla (now LysiosquiUa) glabriuscula, Lamarck. 

 The latter has the dactylus armed with only 57 

 teeth, and sometimes fewer, whereas L. maculata has 

 from 's 10. Ht-rbst's figure, though coarsely executed, gives 

 a very good general idea of the appearance- 



The <:pecific name chosen by Fabricius evidently refers to the 

 colouring of the telson. for he speaks of '' the last segment apically 

 dark, with two whitish marginal spots-" This is quite correct, 

 but the broad distal dark-blue band is so much broken by the two 

 wliite spots that the effect produced would rather lead one to 

 =pcak of 3 blue spots. In Herbst's figure they are quite separated,.
