intervening regions. Pfeffer does not mention in the descrip- 

 tion be gives whether his species is smooth or not, but be bas 

 kindly informed me tbat it is really perfectly smootb. 



Sepia cultrata Steenstrup & Hoyle bears some reserablance 

 to this form in tbe outer parts but bas quite a difFerent sbell. 

 Sepia verrucosa can tbus be regarded as a very good species, 

 parallel, in some respects, to S. singaporensis. 



2.) Oinniatostrephes bartramii d'Orb. sinuosiis ') n. var. 



Diagnosis: Anterior edge of tbe raantle not angular. Fins 

 ■occupy a little more tban balf tbe paliial lengtb, tbeir com- 

 bined widtb being about | of tbe paliial lengtb. Bracbial for- 

 mula 4, 3, 2, 1. Connective apparatus 3 — 4. Number of folds 

 in tbe sipbonal fossa 9 —9 — 9. 



Description: Tbe anterior balf of tbe body is ratber stout, 

 cylindrical, tbe posterior end tapering to a point. Tbe fins are 

 transversely rbomboidal and occupy a little raore tban balf the 

 paliial lengtb (54 %). The lateral angles of the fins are about 

 75% tbe posterior 105°. The combined width of botb fins is 88 % 

 ■of tbe paliial lengtb. The greatest width of tbe fins is situated 

 about 15 mm. anteriorly to the middle of tbe fin. The anterior 

 mantle margin is neither angular dorsally, nor quite straight, but 

 feebly convex; the ventral mantle margin is somewbat concave. 

 The sipbonal fossa is deep and presents anteriorly a large me- 

 dian pocket witb 9 longitudinal folds, and on each side of this 

 are 9 smaller side-pockets. (Fig.) Tbe 9 side-pockets are ar- 

 ranged in tbe following manner: anteriorly three small trans- 

 verse pockets lying ratber close togetber; the fourth is oblique 

 and proximally covered by tbe transverse fiftb, which is situated 

 in tbe same line as the bind margin of the large median pocket; 



I regarded this squid at first as an entirely new species, but niy frieud Dr. 

 Pfeffer of Hamburg has informed me thut the diagnoses cif O. liartramii 

 ia the literature are wrong and partly too narrow, and that this specimeu 

 from Teneriffe must be classed with O. bartramii, though it differs from it 

 in some respects.
