Dear Doctor Schmitt: 
My best thanks to you for having remembered me with the inter- 
esting fresh specimens of chaetopods that you have been taking on your 
expedition. Also, I am very happy to have received word from you in 
spite of your many duties which doubtless take up much of your time* 
We have long been wondering how tilings were progressing in Alaska j your 
timely report is encouraging and stimulating. 
The collections that you have 3ent (and which are going to the 
Museum today or tomorrow) contain the following chaetopods: 
l4-4o* Sept. 18, 1940. Canoe Bay, Alaska. Lot 1. 
Id anthyrsus arma tus Kinberg, subsp. pennarmatus MS - 2 specimens 
and tubes. [I am retaining one j 
This is the same as in the USNM coll. (Alb. 3ta. 2878, Sept. 
25, 1888, from between Sitka and Columbia Hiver, in 66 fms.) 
This species comes near two well known tropical species, - 
I. armatus Kinberg and l* pennatus Peters, but is inter- 
mediate, hence the subspecific designation here proposed. 
Vermil iop sis sp. - on Balanus, in white calcareous tube, with 
strong median carene. 
juvenile sabellid, probably species of Sen izooranchia , in "thin s trd 
tube, attached to barnacle. 
14-40. Lot 2. 
Idanthyrsus arma tus pennarmatus MS (4 specimens). , 
Ps e ud o po ta rni 1 la intermedia Moore (1 specimen and tubes) 
Lag isca , juvenile. (1 specimen) 
Spir or bis , probably spiri Hum Linn. (5 specimens) 
17-40. Sept. 19, 1940. from P. camtschatica . 
Idanthyrsus penna rmatus MS (I ’nave kept 2 specimens out of 6) 
Potamilla neglects (Sara) in long, sand-covered, chitinous tube 
Pseudopotamilla intermedia Moore (forme tube clusters, several spec./ 
Sab el la eras sic o rnis Sars (crown detached from tube with specimen) 
Vermiliopsis sp. (same as in 14-40. (retaining 2 out of 9 ) 
Lagi sea raris pina (Sars) (2+ specimens, scales detached) 
Crucigera zygophora Johnson (1 specimen in tube; 
From Tondeleyo crab trap in Canoe Bay, Alaska... Sept. 25, 1 v40 . 
Cruci gera i rregularis Bush (numerous specimens in white coiled tubes) 
Vermiliopsis sp* (same as in 14—20 and 17—40. (one specimen) 
I am exceedingly curious to know that the tube masses can represent. 
On the whole, that cold-water fauna is rich in numbers of individuals but 
meagre in numbers of species, compared with the fauna of warmer waters. I 
was impressed with the same phenomenon at Beaufort as compared with the 
Dew England forms. 
iith all good wishes. 
Very truly yours.
