10 ZOOLOGY OF THE VOYAGE OF THE SULPHUR. 



transversim striatis ; varicibus senis tenuibus, laciniatis, antice inter lacinias seriebus duabus ele- 

 ganter crenatis ; laciniis acurninatis, uncinatis, gradatim minoribus ; apertura obovata ; canali aperto, 

 ad basin subrecurvo. 



Inhab. Bay of Magdalena, California. From seven fathoms, on a sandy 

 floor. 



Typhis. Montfort. 



18. Typhis quadratus, Hinds, Proceed. Zool. Soc. 1843, p. 18, (Plate III. fig. 3, 4.) Testa 

 subquadrata, fusca vel albida, lineis pallidis transversis ; quadrifariam varicosa; varicibus crassis 

 acutis, ad spiram commixtis, superne nodulosis, in spinis appressis desinentibus ; tubulis subrectis 

 vel deorsiim inclinatis ; canali mediocri laterali. 



Inhab. GulfofNicoya and the Bay of Guayaquil. Dredged from a muddy 

 bottom, in from seven to eighteen fathoms. 



Allied to Typhis Soiverhii, but distinguished from it by its squarish shape, thick 

 and nodulous varices, closely appressed spines, and the decided lateral direction 

 of the canal. 



19. Typhis arcuatus, Hinds, 1. c. p. 19, (Plate III. fig. 1, 2.) Testa cornea, fusiformi; qua- 

 drifariam varicosa ; varicibus arcuatis, inermibus, ad spiram bene distinctis, superne in tubulis desi- 

 nentibus ; tubulis complanatis, ascendentibus ; canali mediocri recurvo. 



Inhab. Cape of Good Hope. Dredged on the L'Agulhas bank in from forty 

 to fifty-four fathoms. 



Shell fusiform, of a horn-colour ; the varices arcuate, terminating in the tube, 

 and ascending the spire even to the apex, giving it a pyramidal shape. The 

 character of the bowed spineless varices is peculiar, and altogether it is a very 

 distinct species. 



20. Typhis nitens, Hinds, 1. c. p. 19, (Plate III. fig. 5, 6.) Testa ovali, albida, lasvigata, 

 nitida; quadrifariam varicosa; varicibus acutis in spinis excentricis desinentibus; tubulis rectis; 

 canali brevi recurvo. 



Inhab. Straits of Macassar, Indian Archipelago. Dredged from among 

 gravel and coral in eighteen fathoms. 



Looking from the apex, the spines and tubes will be seen to be disposed in an 

 elegant spiral manner about the spire. It is the first species, as far I am 

 acquainted, that has hitherto been found in the Indian seas, and is at the same 

 time the smallest yet recorded.
